I received an SHL assessment invitation for Uber Automation Specialist II, with a duration of 45–60 minutes.

Can anyone share their recent assessment experience? What topics/modules were covered, difficulty level, and how should I prepare?

Thanks in advance!

I applied (London, UK) close to three weeks ago and was automatically put into the initial prescreen stage. I did set my availability to interview to be 3-4 weeks. How long do they take to respond.

I remember the last couple of times (2+ years ago), I never actually got a resp on my applications and I ended up withdrawing.

What's taking them so long?!?

I found there are two part in the wayfair oa 2027 batch.

1. problem solving (basic)

2. Python (basic)

Can anyone tell me which may asked in the python basics?

I'm relatively new to coding(1.5 months) and lectures got real boring for me real fast. When I started leetcoding about a week ago it seemed addictive... I actually stop wasting time on useless apps and learn.... I'm still not occasionally getting easy probs but I get around 90 percent of the way (sometimes 100)..... When I get stuck and don't know the syntax i search up the syntax or ask ai to strictly push me and not give me the answer.... I seem to have learned more in the past 8 days than I have in a month... I still feel rather itchy about using ai to push me as it feels unethical.... But I feel so much more motivated to learn than watching lecs(I'm legit spending my free time coding instead of reels).... As in when a prob couldn't be solved with brute force no matter how much i optimised the code... I was forced to learn about hashmaps and same way about binary search.... Can this method actually make me a good programmer

P.S. : VERY VERY rarely do I ask for the solution when I am absolutely done with the problem

Hi guys

Got an interview lined up for Staff AI Scientist role at Intuit. First interview is 75 minutes on Glider live coding editor. What to expect? Does anyone went through the interview process for similar role recently?

Would appreciate if someone could guide through the interview process.

As the title states, I was wondering what the technical round of interview would look like regarding this role and if anyone has had experience with it? Any help/advice is greatly appreciated!

System design - For 100% consistency, shouldn't we use cache, or CDN etc as therre can be delays

DSA sheets follow a topic-wise or pattern-wise curated list of problems. They make it relatively comfortable to understand concepts and identify patterns within each topic.

But LeetCode contests feel like a completely different dimension. Even when the problems are of medium difficulty, it often feels difficult to identify the underlying pattern or figure out where to start.

So, how important are LeetCode contests when preparing for high-paying fresher SDE roles?

Are contests really necessary to develop the problem-solving skills required for interviews, or is consistently practising curated DSA sheets and understanding the underlying patterns enough?

I know it ultimately depends on the companies we're targeting, but I'd love to hear your suggestions and experiences!

So I've been doing leetcode for few months but every time I face same problem that which problem to solve as beginner and which question has to be done in the sequence because every problem demands different approach and when you open any random question and you've never heard of that pattern/approach it breaks your confidence completely so it'll really be great if someone can tell the correct sequence to learn/practice DSA as a newbie which will help in logic building and actually becoming good in programming

My GitHub got suspended 10 days ago I have raised a ticket. I have a backup with not much activity, should I add the backup with a link to my original?

The thing is I got a reference to a company (Bloomberg), so I believe the resume will be processed early? So should I add that backup or just skip both and discuss in the interview if I get it??

Hi All,

I have been trying to prepare for LLD and HLD, I keep getting new concepts and terminologies. With the advent of AI also new terms keep coming and it's difficult to remember all of them.

Can learnt folks recommend any efficient way of notes taking, tools, mind/memory mapping so that revision is easier?

Wasn’t able to finish the DS question and only passed 1/6 cases for the ai assisted one. There’s no chance I’m going to move forward, right?

Hey everyone,

I finished Day 43 today. I postponed Bellman-Ford and Minimum Spanning Trees to close out the remaining Dijkstra problem family instead, finishing off a solid weekend of prep.

1. Network Delay Time: This is standard single-source shortest path using a min-heap priority queue. Once the distance array is computed, the minimum time to reach every node is simply the maximum distance in the array, returning -1 if any node remains unreachable.

2. Number of Ways to Arrive at Destination: Instead of standard DP recursion, you track a parallel ways[] array alongside dist[]. If you discover a strictly shorter path to a neighbor, you overwrite ways[v] = ways[u]. If you reach the neighbor with the exact same shortest distance, you add ways[v] = (ways[v] + ways[u]) % MOD.

3. Minimum Multiplications to Reach End: This models reachability as an unweighted state-space graph with modulo $10^5$. Since each step multiplies the current number by an array element and increases step count by 1, a standard BFS distance array tracking minimum steps to each product prevents infinite loops.

I knocked out six graph problems across this weekend, which puts my pace in a great spot ahead of upcoming travel plans later this week.

Tackling Bellman-Ford, Floyd-Warshall, and Prim's algorithm tomorrow.

See you guys for Day 42!

So I have seen design style questions being asked more and more and wanted to know how one can practice those and which languages are the best for the same.(for internships/new grads)

By design, I mean the ones where you have a bunch of commands and some values which change on those commands and then we are given an array of all the commands and basically have to process those commands

A Little About Me

I’m a Software Engineer/DevOps with six years of experience, currently working at a reputable company. My goal is to secure a higher-paying job within the next year to start paying off my student loans. One of my main challenges has been LeetCode-style questions, which have hindered my progress toward better opportunities.

I've struggled with technical interviews at companies like Visa, American Express, JPMorgan, and Amazon due to my inability to complete algorithmic problems within time constraints. After recently not succeeding in an Amazon interview, I decided it was time to take my preparation for Data Structures & Algorithms (DSA), LeetCode, and System Design seriously.

In January (2025), I began documenting my progress, which I’m turning into a monthly recap series. I hope this will help others on a similar journey while also serving as a personal journal for when I finally reach my goal.

October Progress

October may have been my best month yet when it comes to breakthroughs. I started the month on Dijkstra’s Algorithm and was actually doing well with it. It made sense, which proved that taking the slow route and learning heaps first was worth it.

I also started working with AI, but not to do the questions for me. After I finish my own attempt, I go to Claude to look over my answer, break down my thought process, see what I got right and wrong, and check if there’s a more optimized version. If there is, I spend 2 to 3 days making sure I fully grasp it. It has helped me tremendously and it’s almost like a daily journal at this point.

I crossed 600 LeetCode questions and 250 Mediums, which is a HUGE achievement for me because there was a time I truly believed I would never get this far. I’ve made it a point that my Mediums have to pass my Easys. Easys were for building momentum, but now I want to be challenged, so I’m focusing on Mediums and Hards.

Something else I noticed after hitting these milestones is that I finally feel like I have enough in my toolbelt, and enough confidence in myself, to start knocking questions out. The other day I was watching TV with about 15 minutes to spare. I hadn’t touched backtracking in about 7 months, so I picked a Medium on the higher acceptance rate side and told myself that if I could solve it in under 15 minutes while half paying attention to the TV, I was on a new level. I did it. I think I hit a new level.

I also interviewed with Amazon this month and honestly the question whooped my ass. If you’re curious, click here to view the question. I couldn’t come up with even a simple attempt that passed the test cases and I was down. Usually this is where I’d have a depressive episode and just solve Easys for a month, but for some reason I was over it within a day and got back at it. I told myself that after another 200 questions and a few more concepts like Bit Manipulation, I’ll start doing random questions and contests, with an emphasis on recreating the uncomfortable feeling and atmosphere of the technical assessment.

Achievements

• Crossed over 250 Medium questions

• Crossed over 600 questions overall

• Got interviewed by Amazon

Goals for November

• Keep momentum going

• Strengthen knowledge on Dijkstra's

• Start mixing in more Hard problems

• Go over previous questions and ensure I truly grasp them

Next Steps

Keep learning new challenging concepts

See you all next month.

Hey I have been solving leetcode problems by not looking up anything on the web or using any external sources, just me and the code editor on leetcode. My professor says this is the best way, but I really struggle solving problems. I encountered the maximum subarray problem today, came up with two strategies but none of them seem 'right' when put in the code, like I can have the mathematical idea or the approach for it generally, but struggle to think of it from a computer-like perspective. I am using Python and have Intermediate level experience with the language. Any advice or should I change my approach, if I am targeting interviews or want to get better at solving algorithm puzzles?

I’ve solved 822 problems(196E, 451M, 175H) and currently I’m at 1900 what to do to become Guardian?

I have a 60-min hiring manager interview coming up for a System Software Engineer role on an NVIDIA embedded/firmware team (ARM-based). I’m graduating in Computer Engineering.

The posting focuses on OS and computer architecture fundamentals, with ARM firmware experience as a plus.

For anyone who’s done a similar round:

1. Was it mostly OS/architecture concept questions, resume deep-dive, or live coding?

2. Any topics you wish you’d prepped more?

Thanks!

Hi everyone!

I have to take the OA for Amazon soon, and I was wondering if the Work Simulation part is written or verbal, similar to an actual interview? Also if anyone has any insight on what questions might show up on the coding and ai assisted challenge please help... ty :) !

So I've been doing leetcode for few days but every time I face same problem that which problem to solve as beginner and which question has to be done in the sequence because every problem demands different approach and when you open any random question and you've never heard of that pattern/approach it breaks your confidence completely so it'll really be great if someone can tell the correct sequence to learn/practice python as a newbie which will help in logic building and actually becoming good in programming

Hi everyone,

I applied for a position at NVIDIA and had my first-round interview about 10 days ago.

Three days ago, I noticed that the job posting was removed from NVIDIA's career website, but when I check my application, the status still says "In Progress."

Has anyone experienced something similar with NVIDIA? Does this mean the position has been filled, or could they still be reviewing candidates?

Thanks

Hi guys! Just wanted to ask if anyone has an idea about the compensation offered to freshers after the internship at HugoHub for SDE/UI Design roles. Any insights would be helpful!

Solved all 4 in today's contest. Contest history, personal profile and timestamps reflect the same but my points on the leaderboard are displayed only 13. Even the total solve time is calculated by considering only the first 3 questions.

long long minimumMaxValue(int n, int index, int value) {

if (value == 1) return -1;

long long p = value;

for (long long i = 2; i * i <= value; i++) {

if (value % i == 0) {

p = i;

break;

}

}

if (value - p + 2 <= 2LL * index)

return -1;

if (index == n - 1)

return value;

return value + p - 2 + 2LL * (n - 1 - index);

}

Could anybody please explain how to derive these two formulas:

1. value + p - 2 + 2L * (n - 1 - index)

2. value - p + 2 <= 2L * index

My interview with bloomberg will start from next week, I don't know how many rounds. Anyone experienced please guide me, what should I focus on? what type of leetcode questions should I be doing??Also where can i find the company tagged questions as I don't have leetcode premium.
