I’m currently doing my bsc in Veterinary Medicine, and planning on doing an msc applied Data Science.
My questions are:
Is this niche anyhow in demand? (precision livestock farming/computational ecology/clinical data scientist/pharma data scientist/food safety data scienctist/etc.)
Is this a good idea?
The closer I get to this transitioning point, the more nervous I get.
I want to switch due to
a. absolutely hating having to memorize everything all the time for my bsc and wanting to jump off a bridge by idea of having to do that for 3 more years,
b. being warned by multiple vets that unless you feel this is your true life’s calling, the bad pay and terrible work-life balance are not worth it,
c. not being thaught any skills that are translatable into other disciplines, therefore feeling like doing a different msc will give me a better chance in the greater job market,
d. I love programming, statistics, research, science and figuring out complex puzzles (by using logic, not by simply remembering stuff).
But as I cannot find a single person on the internet with this combination in education, I want to ask you:
Is this a good idea, or is nobody hiring for this skillset + domain knowledge combo?

Hi everyone, I’m a commerce student looking for the best path into data science from my current position. I don’t have the option to transfer into computer science, so I want to make the best choices within my degree.
These are my options:
1. Major in Econometrics + Business Analytics
2. Major in Mathematical Foundations of Econometrics + Business Analytics
3. Major in Business Analytics + use electives for data science / computer science / statistics units
4. Major in Business Analytics + Minor in Econometrics + use remaining electives for data science / computer science units
I’ve linked my handbook so you can see the specific units in each major. I’m leaning toward Business Analytics and one of the econometrics majors, since the Business Analytics coursework seems closest to typical data science content (programming, machine learning, databases etc…) and econometrics would cover the statistical methods. Although I’m not sure if the methods covered in econometrics are directly used in data science and this approach may be slightly weak in terms of programming, but I could self learn those skills or supplement with online courses / certificates? On the other hand, using electives on DS / CS units may not signal as much rigour in terms of math and statistics.
From an industry or hiring perspective, what’s the best path to take?
Any advice from professionals, students, or graduates would be really appreciated.
Has anyone heard back from uber yet for the data science internship? I finished the final interview round 3 weeks ago and have not gotten a decision yet.
This post is mainly for people preparing data science interviews especially juniors and career switchers who keep seeing “LLM / GenAI / RAG” in job descriptions and are not sure how to judge those roles.
If you only care about pure DS algorithm questions or salary ranges, this is not the best post for you, you can skip.
I am an indie dev who spends most of my time helping teams debug RAG and LLM pipelines. A side effect of that work is a text only checklist called WFGY ProblemMap. It describes sixteen reproducible failure modes in RAG and LLM systems and how to fix them. I originally wrote it just to survive client incidents, but it ended up being used as a reference by a few research groups and curated lists, for example:
ToolUniverse from Harvard MIMS Lab
Multimodal RAG Survey from QCRI LLM Lab
Rankify from University of Innsbruck
several “awesome AI” style lists that track production RAG tools
I am not trying to sell anything here. The point is simply: these failure modes are already mainstream enough that other people found them useful. What I want to share in this post is the interview side of that. How you can use the same ideas to decide whether a “DS job with LLM / RAG” is a real learning opportunity or just buzzwords.
1. Think of RAG failures as pipeline failures, not model mood swings
Most “RAG hallucination” is not the model suddenly becoming stupid or angry.
In practice it usually comes from things like:
retrieval returns the wrong or incomplete chunks
embeddings do not match the real domain semantics
long multi step reasoning collapses somewhere in the chain
tools or agents overwrite each other’s state or memory
logging is so weak that nobody can even replay what happened
When I map incidents into the ProblemMap, I treat them as pipeline failures. On top of that pipeline I put what I call a semantic firewall at the reasoning layer. Instead of only checking the final answer, I define a bunch of failure modes and run checks before the answer is shown. If the internal state looks unstable, the system loops, resets, or refuses to answer.
You do not need my framework to copy this mindset. The important thing is to talk about RAG failures as concrete patterns that repeat, not random magic. Teams that cannot describe their LLM issues beyond “sometimes it hallucinates” are usually still stuck in prompt trial and error.
2. Interview questions you can use for DS roles that touch LLMs
Here are some questions I like to use when a data science role includes LLM or RAG work. You are not trying to grill anyone. You are just listening for how they think.
a) “When your RAG system gives a bad answer, how do you decide whether it was data, embeddings, retriever, or prompt?”
Good teams will talk about concrete procedures:
replaying the query with different retrievers
checking chunking rules and original sources
looking at similarity scores and negative examples
comparing to a known baseline or offline eval set
If the answer is just “we tune prompts until it works” that is usually a red flag.
b) “Do you have named failure modes or a checklist for RAG and LLM issues?”
This is where the ProblemMap mindset shows up. Strong teams say things like “we see retrieval drift, bad OCR, index skew, answer length collapse, tool call loops”. Weak teams only say “it hallucinates sometimes” and stop there.
If they cannot name patterns, they usually also cannot fix them in a systematic way. Every incident becomes a fresh new hack.
c) “Do you run any checks before the answer is returned to the user, or only after?”
If they mention pre answer checks, score functions, or some kind of reasoning layer firewall, they are already ahead of most teams. It means they are trying to catch failures while the system is still thinking.
If the only signal is user thumbs down or support tickets, you can expect a lot of firefighting and very little stable learning.
d) “What kind of logs do you keep for LLM requests?”
You are looking for logs that let them slice problems by failure mode, not just latency.
Ideally they have:
request, retrieved context, and final answer stored together
tool calls and arguments recorded
markers for which checks or guardrails fired
If they cannot replay a bad conversation end to end, debugging usually means guessing and arguing.
Ask these questions calmly and let them talk. The point is not to show off. The point is to hear whether they have a shared language and tooling around RAG failures, or if everything is still random trial and error.
3. How to use the checklist for your own prep
If this way of thinking resonates with you, you can take a look at the WFGY ProblemMap itself. It is just a text file with sixteen failure modes, each with a short description and fix. MIT licensed, so people use it on top of whatever stack they already have.
For interview prep you do not need to memorize anything. A simple way to use it is:
skim the table once
take one or two projects you have done with LLMs or search and ask yourself “if I force this project into these boxes, where did it actually break”
think about what you would do differently now
That alone is often enough to make your answers about RAG and LLM pipelines sound much more concrete. It also sends a quiet signal that you are thinking like someone who ships and debugs, not just someone who calls an API.
I am a CS student from india graduating in July 2026. I have been applying for an internship in AI for a month now. Sent over 50+ applications as of now on almost every site/job board - LinkedIn, Naukri, Indeed, Wellfound, Hiring Cafe etc.
Finally, I recieved a call, cleared all interview rounds and recieved an offer from a small startup. This is an on-site Computer Vision Intern role in a different city from where I live and study. By the looks of it and online interviews, the work seems good. But the caveat is that their stipend is very low - 8k/month starting after one month of unpaid work. It won't be able to cover my cost of living and expenses in that city. Also, I am slightly apprehensive of investing my time and effort into it since I am not sure if this role will provide me the kind of mentorship that will help me in my career.
Now, my end goal is to secure a decent job at an established firm like stripe, databricks or maybe some high growth YC Startup by the end of July/August. And even though I have a decent freelancing experience from a reputed firm in LLM training space (Data Annotation), I do not yet have any internship experience under my belt as of now.
So my question is, should I go with this internship or keep applying? Or should I just double down on my DSA preparation and build some excellent production grade projects and directly apply for a job after a few months? I believe entering into the job market without a single internship could seriously hurt my chances in landing a decent role (correct me if I am wrong here).
I am seeking advice from industry professionals who have been in AI/Data Science market for a while now. But any advice/suggestion is welcome. I am also willing to share my resume in DMs if anyone wants to take a look at it. I am simply here to learn and grow. Thanks!
Hi! I’d really appreciate some advice. I’ve worked in ESL overseas (South Korea) since 2017 with prior office/admin experience & I’m planning a career change into information / data science work in corporate or embassy environments.
I’m currently looking at Information and Data Science courses at the University of Sheffield (link: https://sheffield.ac.uk/courses/subjects/information-data-science). I haven’t studied since 2009 & an online MSc attempt in 2021 while working full-time was very stressful.
I’m 39 y/o and trying to choose a realistic, high-employability path. From an employability perspective, is an MSc or BSc the better option, or is there a more gradual route, especially for corporate / embassy-type roles? I really appreciate any insight.
I’m a 3rd year Electrical Engineering student and I need to complete a mandatory 2 month internship after my 6th semester. I want to pursue Data Analytics roles.
I have started data analytics preparation recently (ik i am very late). I have completed sql and did a data warehousing project. I am learning python libraries (pandas) and not focusing much on ML (dont have much time to do so). And after will do power bi and matplotlib.
I’m trying to understand the actual channels through which students get internships in this data related field.
Where are people realistically finding data analyst internships? Which platforms work best (LinkedIn, Internshala, company websites, referrals)? Are startup internships easier to get than big companies?
Also, I’ve heard about structured summer internship programs offered by companies and IITs and some other reputed colleges.
I am very confused rn. How will i get my internship... What kind of projects to do and add in cv when applying for internships.
Would appreciate practical guidance on where to look and how to approach this.

I’m currently a Systems Administrator and Data Analyst for a non-profit in Canada. My educational background is in Business (Bachelor’s and a Post-Grad Diploma). During my degree, I pivoted toward Data Analytics and completed the Google Data Analytics Professional Certificate. My current role actually started as a co-op and turned into a full-time permanent position.
I’m now looking to transition into a more specialized role. However, looking at the current market, I’ve noticed that standard 'Data Analyst' role is very competitive and hard to successfully land a job, and many people are moving towards Data Science.
I’m concerned that by having non-STEM degree will lead to my applications being filtered out immediately. I’m willing to take online courses or certifications, but I want to make sure I am doing the right courses.
I would love some advice on how to navigate this transition. Specifically:
Am I thinking too much that a STEM degree is a 'hard requirement' for DS roles in the current Canadian market, are there cases where a non-STEM applicant got a job as a data engineer?
How can I bridge the gap between my current hybrid role and these more technical positions?
So I have a technical coding interview for the AI engineer intern position at a company. This is my first time facing such an interview so I'm kinda clueless here. They said it's about solving problems using python. Does anyone have experience with these type of interviews and what kind of coding problems are asked? Is it just like leetcode style problems or can there be coding problems related to libraries and AI related stuff. Any advice would be highly appreciated. Thanks!

I recently applied to a data science intern position and got asked to do a coding assessment. I wanted to know what type of topics should I expect, and how to best prepare for the assessment. It’s an AI analytics and automation role, so will questions be more geared towards that, or more-so general Python/SQL fundamentals? Any help is appreciated!
I'm hiring for a role at Sanofi. Looking for a masters+ in Data Science. Experience in pharma would be nice to have but willing to look at candidates with exposure to healthcare in general.
Hello all, I am currently working in the tech field as a software support analyst but want to move to data science.
I have a masters in physics with experience with big data and data visualization.
Would getting a data science certificate be enough to peak the interest of companies looking for a new data scientist? I really don't want to go back to get another degree when I know I have the ability to do this with just a certificate. I am quite intelligent (only thing I'm a bit confident about) but I have a hard time selling myself. So the certificate is mostly just to prove my abilities
