Matrix IFS
- Largest island size matrix question. How to solve if matrix has billion rows? Any ideas? Thanks in advance.
- Interview question follow up: what about if matrix was really big? What are interviewers looking for when they ask a followup that says the matrix was super big like 100M x 100M? That we just read the board line by line (4kb) and it cant fit in memory?
- How do people get through difficult assessments Just gave a codesignal assessment for Uber. I essentially solved only the two basic questions they put in there to see if you can code. There was this matrix question that looked doable but I couldn't figure out how to do it for the life of me. And for another question, I simply did a brute force, a
- Roblox OA be like If you're given an input "L1", reflect your matrix over y=x and gently insert your index finger into your anal cavity. If you're given "L2", force your entire fist up there and rotate it 90 degrees counterclockwise. I love CodeSignal 🤗🤗 TC + YOE = 0
- How would you solve .. array doesn't fit in memory questions? Many companies including Google ask these type of questions for follow ups on leetcode. How would you solve if a 2d matrix doesn't fit in memory or a string doesn't fit in memory type of questions?
- How to solve graph problems? I have been trying to practice graph problems and im really struggling. I can do basic dfs/bfs on adjancency list i have some understanding which approach is decent in which situation. Hell, i even understand union find and topo sort and can implement those. But LC problems are insanely hard for me
- Would everyone in FAANG companies know how to find “longest palindromic string” in a 1000 letter string? How much is this for real? Is this the best matrix to find out what you could or could not do? We all know in real world, there are more than few other tasks one needs to perform besides (finding a palindromic string not sure if they do). Is leetcode the only way to get a job in SV, let alone beside
- SDE 1 vs SDE 2 which interview is harder at Amazon? I have a final round interview with amazon in few days. 4 interviews on one day. I just wanted to know which level interview is harder SDE 1 or SDE 2 ? I have SDE 1 interview but I applied for SDE 2 position. And I was told that if I perform well I will bumped to L5 Also. What are the data structu
- Will TTWO stock $ triple in next 5 yrs? I don't understand why Roblox's market cap is 2.5 times as many as TakeTwo Interactive's (50b vs 20b). TakeTwo has created the greatest ever open-world games like GTA and Red Dead Redemption while Roblox just make some mobile games for kids. I personally think TTWO stock is highly underestimated be

- What's the best approach for 2d array problems? I thought it was rare (and also pretty straightforward) and didn't bother practicing, but just got three in a row. 2 on one on-site and I couldn't finish any of them. My basic approach is to write an embedded for loop and parse the entire matrix, however this requires a lot of code and I'm not sure
- Dear Interviwers Dear Interviwers, Please stop asking f***king question. Print all elements of the matrix in spiral order. People have been asking me same question for almost 10 years. For god sake I know the perfect solution and I cannot pretend as if I have seen this question 1st time. I am sure it will be same w
- If you could hold the Facebook pixel in your hand, what would it look like? I like to imagine the Facebook pixel to be like the "fix its" from classic 80s movie "batteries not included", navigating through a matrix like system. It needs our guidance at first but finds its own way and delivers results if you become it's friend and trust it. So it begged the question... What
- Do i deserve reply and retest ? I gave a coding round for startup for data science and only R,python were provided in options. I had practiced DSA problems only in C++ and don't use python and R regularly (I used them for specific projects in data science). I would have solved both problems in 15 minutes if C++ was allowed. Also
- Should I not try to get into faang if I fail phone technical? I’ve recently interviewed with Microsoft for 2 different teams. Both questions for the two separate coding questions were 2d matrix related. I did about 10-15 leetcode questions before and didn’t see any 2d matrix problems. I got to a solution in both but struggled a bit and did not move forward in
- Are LinkedIn interviews scripted? Interviewed with LinkedIn (AI org) last week. I got this weird feeling that their entire interview process is scripted. In the sense that the interviewers have a repository of questions and they choose one of those questions. In fact it seemed like they also have expected answers for those questions
- Bar for Hiring - Roaming Cats Challenge I was given this problem at Texas Instruments this morning after implementing three other algorithms like Radix sorting, Spiral Matrix II, and a farming DFS challenge. I had 8 minutes left to bang this one out, so after I decrypted the weird wording, I started working up a solution around Djikstra's
- Amazon On-site experience Hello, In SDE2 interview, I was asked couple of hard questions and one weird medium matrix question which I couldn’t get the logic and was helped in the end on the medium to solve it. I could not solve any of the three coding questions at the end. The design question was expected and easy. I see h
- Mind Blowing Reading about the hiring games the big tech companies reminds me of people being interviewed to plug into the Matrix and being consumed to power a monolithic evil intelligence. You shouldn't have to justify your existence, personality, etc. to a bunch of self-important soulless idiots and play the
- Intuit ML engineer interview I have an upcoming onsite interview with Intuit for ML Engineer role. I am confused about the craft demo requirement. If you have attended ML Engineer interview at Intuit could you share the type of questions you were asked for craft demo round? Do they provide a dataset and ask me to implement a
- Recently Asked Interview Questions Hi, Here are list of questions asked in recent interviews - 1. Check if there is path from node 1 to last node in 2D matrix. 2. Group Anagram 3. Merge Intervals 4. Get the shortest path in graph 5. Get the data from API in Jon format and bind the HTML controls 6. Copy linked list with random point

- Finally, Zuckerberg’s ego costs him his company For years this moron thought he was actually smart because he was lucky enough to have good connections and hire smart people. This allowed his ego to grow unchecked, until now. The years of delusion and yes men have finally caught up to him. The Meta verse is a joke and the worst product directio
- Google Interview Question Interview question: Given a matrix m*n with value as C, S,E,1 C: customer S: start index E: end index K : 2 Question was: if there exist any route from S to E where movement is allowed horizontal and vertical(not diagonal). Yo need to maintain k distance from C(because customers r corona infecte
- vote Hot take: DPs are not hard Sure if the interviewer wants you to jump straight into the Bottom-up Tabulation method then it is tough. But honestly no one really requires that except for a few exceptions. A top down recursive solution with memoization is enough. 1. Figure out the recursive formula to get all possible results
- Revisit algos you have already done How do you find time to revisit algos you have done? I got a max subarray question today for example and I just couldn't recall kadane's algorithm. Having solved so many, I am totally lost if I randomly pick one that I have already done in the past. I also got the spiral matrix question last week an
- Google L4 onsite I had my onsite recently. 4 coding + 1 behavioral. 3 coding went well with optimal solutions and the interviewers looked happy. 1 was kind of ok. It was a matrix question and the interviewer was strict and did lose calm once or twice during the interview. Started with a brute force solution and re
- Switching during parental leave? I'm considering changing companies for relocation purposes during my parental leave because my team doesn't allow working remotely. I wasn't able to find anything suitable for OOM internally and found something external instead. Does anyone know if switching companies during parental leave comes wi
- SWE needs to have 2 kind of skillset 1- to crack interview 2- to do the job Most of the junk asked in interviews is not required at real job. For example - They would ask complex sql queries in interview while on job very simple queries required. Even for complex queries,if ever required on the real job, all I’d need is stackoverflo
- Abandon Ship after 3 months? Have you ever started a role with a new company and realized in short order the place is a hot mess, so much that it's difficult to get to meaningful, strategic work due to all the red tape? Maybe I missed this or didn't ask the right questions during the interview process. There's so much wasted m
