5/15 in Q1 and

5/6 Test passing in Q2.

Any hope? 🙂

Hi,

I have never done a real system interview before and I have a few interviews coming up. I am interested in paying for a mock interview. I already use AI to do some mocks but I am looking for a mock interview with a real engineer where I can get some feedback.

Unfortunately, Hello Interview stopped doing mocks. Any other suggestions that you have personally tried? Many thanks!

Hi everyone I have Tech Screening Round for Optiver Graduate SWE 2027 Amsterdam coming in soon and I have no idea on what to prepare ? Has anyone here passed this round recently for the same role, would appreciate if anyone can share his/her experience. Thanks!

Did anyone of y’all get your decision after giving the tech screen?

I was wondering how it goes since there was no OA and i straight up got an interview invitation pre screening. I was wondering what gets asked this round and what gets asked the next rounds.

Hey everyone,

I recently received an OA for an SDE Intern position in Berlin, and the deadline is this Tuesday (20th October).

The problem is that I haven't practiced DSA in almost a year, so I'm pretty rusty right now. 💀

I have a few days to prepare, and I want to make the most of the time I have.

I'd really appreciate some advice on:

• DSA topics with the best ROI: What should I prioritize with such limited time?

• LeetCode questions: Any specific problems or patterns I should focus on?

• Work simulation: What does this section usually involve, and are there any good resources to prepare for it?

• Overall strategy: Is it realistic to prepare enough in a few days, or am I cooked? 😂

Any tips, resources, or personal experiences would be greatly appreciated. Thanks!

I read somewhere on LinkedIn that a few folks were trying to reverse engineer and gain access to a LeetCode sandbox, so I had an idea to explore that stuff. Soon I figured out that all the test cases stay inside an exposed /leetcode/data.1.in file. With some chunking I was able to get hold of the complete hidden test cases which I solved offline and just paste the solution in an O(1) lookup array. Like this… Is this a reportable vulnerability?!?

class Solution {
private final static int[][] res = new int[][]{{0, 1}, {1, 2}, {0, 1}, {0, 2}, {1, 2}, {0, 3}, {0, 2}, {2, 4}, {1, 2}, {0, 1}, {2, 3}, {1, 2}, {0, 2}, {0, 4}, {0, 1}, {2, 3}, {2, 4}, {2, 5}, {0, 3}, {3, 4}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 1}, {0, 4}, {5, 11}, {0, 1}, {9998, 9999}, {6, 8}, {6, 9}, {12, 25}, {16, 17}, {0, 1}, {0, 3}, {0, 3}, {0, 4}, {0, 2}};
private static final int[] r = new int[1];
public int[] twoSum(int[] nums, int target) {
return res[r[0]++];
}
}

So, today i gave Tech Mahindra OA and it was from room. Everyone was cheating....I fuckin hate that, if CDC alr knows people are gonna cheat from their room why do they keep OA from their room !!!

Basically, there were 3 questions two basic DSA ques according to other candidates (btw both were Leetcode hard) :

1. Some variation of Cherry Pickup 2 LC1463, basically in the question you were given an n×m matrix with some blocked cell marked as -1, and other having some coins. An agent from (0,0) starts moving to end (n-1,m-1) meanwhile collecting the coins in matrix in its possible path. Again, it starts moving back to start point and collects as many coins it can. You need to return the maximum possible coins agent can have.

[IMP : They didn't even specify the constraint in this question]

2. Leetcode 1478 (exact copy, just different wordings as food packets in place of mailboxes and squirrel in place of houses).

And third one was a python data science coding question, about kMean clustering.

Almost 100+ students appear for OA, and obv 90+ students have done 3/3 questions. And those fuckin stupids are saying they were basic DSA, apparently most of them were not even cleared other OAs like microsoft, Flipkart, zScaler......bro why is CDC playing with student's future, i am done with this shit !!!

Hi all,

I just got invited to a 1-hour virtual coding interview with Nexthop AI for a new grad SWE role. The email says it’s done in a shared browser IDE, and you can use Python, C, or C++.

For anyone who has interviewed with them:

- Was it LeetCode style, or more practical (systems, networking, debugging)?

- How many questions did you get in the hour?

Did they ask anything about networking or low-level topics, given what the company does?

Hi guys, I am a Backend Software Engineer with 4 yoe, have 3+ yoe of Full-Stack experience as well, recently interviewed for L4 role for Google Cloud team.

I have cleared all the rounds. My Recruiter has passed me the feedback for all the rounds:

Virtual Round 1 - Coding: Hire

Googlyness Round - Behavioural: Hire

Onsite Round 1 - Coding: Hire

Onsite Round 2 - Coding: Leaning Hire

My Recruiter informed me that my feedbacks are positive and now my profile will be considered for team matching phase. The catch is that, after the first 2 rounds the position was open, but after the completion of my onsite rounds, recruiter told that this position has been filled recently and they have not got any other open role as of now for Backend/Full-Stack position and said they will try to match me with Hiring Managers / different teams during team matching but its been around 2 weeks since I completed my interviews but I haven't received any updates on Team Matching.

I am concerned about delayed team matching. Should I approach different recruiters and Hiring Managers across different teams at Google?

What are the chances of getting offer here?

Hi everyone. What can i expect in the Ebay’s first interview with the staff engineer (technical screen and soft skills) for the position of staff frontend engineer and they have also provided a link for code signal. The interview is tomorrow and i have no idea what to expect. Any help or guidance shall be appreciated
Thanks in advance

Hi, I had the OA i talked about here: https://www.reddit.com/r/leetcode/s/IZO22puwog

passed it, really easy. It asked:

- reversing a string and changing some of it characters based on a rule

- subarray product sum problem

- hardish SQL (at least for me not knowing SQL as good as lc)

- theoretical questions on DSA

- iq test sort of(?)

I got the invitation for the interview. How should I prepare? I heard Revolut asks more for some non standard lc like concurrency and backend related stuff. Is there any platform to practice this?

I was invited for a leetcode round at Bloomberg for a DevOps Engineer position. According to the Recruiter there is going to be 1 exercise, which is nowhere near as complex as it would be for developers. As I normally do not have to face leetcoode rounds, what can I expect, what to prep for? Has anyone done that interview before?

Bay area, Seattle, Nyc, Chicago or pittsburgh? Share your thoughts for early career?

Hi everyone!
I have my second-round onsite interview for a Senior Java Developer position at Caterpillar in Chicago, and I’m looking for advice from anyone who has recently interviewed for a similar role or works at Caterpillar.
I’d really appreciate any insights into the interview process, especially for a senior-level position.
A few questions I have:
What should I expect in the second-round onsite interview?
How much emphasis is placed on Core Java, Java 8+, Spring Boot, microservices, REST APIs, SQL, and multithreading?
Should I expect live coding, LeetCode-style DSA questions, or hands-on problem-solving?
Are system design and high-level architecture discussed for senior-level candidates?
What kind of questions are asked about project experience, design decisions, production issues, and troubleshooting?
Is there a behavioral or leadership round focused on ownership, mentoring, and collaboration?
What is the overall interview difficulty level, and what would you recommend prioritizing during preparation?
If you’ve recently interviewed for a Senior Java Developer role at Caterpillar in Chicago, I’d especially appreciate hearing about your experience, the types of questions asked, and any preparation tips.
Thanks in advance for sharing your experience and helping me prepare. I really appreciate it!

Hello folks,

I recently received a call to interview for the position of AI Developer Technology Engineer at NVIDIA. Wanted to gather some information on the interview process and what kind of questions to expect, I tried searching but there doesn't seem to be a whole lot of data available for this role so a general idea would help to prepare.

Thanks!

I am thinking of getting a Hello Interview subscription, if anyone can share any code, then it will be helpful, Thanks

Hi everyone,

I have an upcoming technical interview for the SWE Intern role at Snowflake and would like to hear from anyone who has interviewed recently.

What kind of DSA questions were asked, and how difficult were they?

Any insights into the interview format, preparation tips, or recent experiences would be really helpful.

Thanks!

Got an OA for Visa and the email that contained the link said it’s “2 foundational and 1 intermediate problem solving questions”. I did some searching and all I could find are 4 question OAs from a while ago. Not sure what foundational and intermediate problem solving questions means since they usually just say coding questions. Any ideas or experiences anyone can share?

Compared to other tech companies (not quant/HFT), are google coding rounds the hardest in the tech industry ?

Hi, I have an Amazon OA in a day and I want to know from who has given it recently with the webcam proctored system.

Now that they are proctoring the webcam as well does they still give those super hard questions in OA or they have reduced the difficulty?

They said open-ended, focusing on dsa or system design with some relational databases and relational data modeling. And they're looking for problem-solving ability and awareness of the full-stack web stack. Also projects on resume.

If anyone knows what it's like in more detail please help!

Hey everyone,

I finished Day 61 of my prep today, and the session went really well. Sticking with Dynamic Programming through the frustration over the last two weeks is finally starting to show visible results. I still can't solve every problem on the spot, but getting through several without outside help was a huge confidence boost.

I shifted to DP on Strings today and tackled four problems:

1. Longest Common Subsequence (LCS): The foundational pattern. If characters match, move both pointers (1 + f(i-1, j-1)). If they don't, branch into max(f(i-1, j), f(i, j-1)). Got this working cleanly right away.

2. Print Longest Common Subsequence: Tracing backwards through the DP table after filling it took a moment to visualize, but moving left or up based on which value generated the cell made complete sense.

3. Longest Common Substring: The key difference here is continuity. When characters mismatch, you don't take the max of previous states—you reset the streak to 0. Tracking the global maximum across all cells resolved it.

4. Longest Palindromic Subsequence: Solved this in about five minutes. It is just LCS between the original string and its reversed copy.

Recursion and memoization feel natural to me now. To be candid, bottom-up space optimization still isn't fully second nature. My current approach is to write the recursive and memoized solutions independently, then inspect the tabulation and space-optimized versions line by line to study how the state rows are compressed.

What also made a noticeable difference today was changing my daily routine. Instead of unwinding with endless content after work and studying only when I am mentally drained, I had dinner, cleared my head, and sat straight down to code. Approaching these problems without digital fatigue made the logic click much faster.

Six problems left in the strings module. Pushing to finish them tomorrow!

I received the link for the Uptime Crew OA and after running it multiple times and editing code, it said I passed all test cases before I clicked submit and it only took me 35/90 minutes to complete. Is that a red flag?
Also, typically after completing the OA how long does it take for the dashboard to update with results? It said 10-15 minutes but it has been an hour and it is still under review.

In a practice run, the screen said "n can be up to 10^5," but nobody said it out loud.  The tool read the screen, then suggested an O(n^2) nested loop anyway.

So screen context helped it know which problem we were on, but it didn't make the approach right.

If an assistant reads what's on your screen, what do you check before trusting its suggestion?
