Hello LC Community,\n\nBefore sharing my interview experience with Facebook and Uber, I would like to thank LC community who helped me a lot to improve my problem solving, data structure and coding skills.\n\nFacebook Rounds Details\n\nPhone Screen\n* Interviwer was very polite and friendly. He started with an array problem (LC Medium) and I explained him the optimal solution. He asked me to write the code and i was able to complete in 10-15 mins. Then he made some changes in the same problem and asked me to provide the solution. I explained my appraoch and complete the code in next 10-15 mins.\n* He was looking impressed and he asked me one more problem LC Hard. I thought about it for next 5 mins and share the approach. He was looking fine with the apporach. Didn\'t write the code as no time left.\n\nRound 1 (System Design)\n* Interviewer asked me something related to design privacy management in FB. I started with functional and non-functional requirements and share my data modelling apprach. \n* Then he changed the requirements. I explained him a more generic approach to handle it but he didn\'t seem confident.\n* I think this round didn\'t went well for me. I feel he changed requirements very frequently instead to listen to my appraoches.\n\nRound 2 (Coding)\n* Interviewer asked me BST (LC Medium) related question and i was able to complete it 10-15 mins.\n* He asked me a followup question and i  was also able to write the code in next 10-15 mins.\n* Interviewer was looking happy with my appraches. This round end up in 30 mins only.\n\nRound 3 (Coding)\n* Interview asked me String (Anagram related (LC Hard)) related question. I gave him the apprach and he was fine with that. I wrote the code and did some dry run. Interviewer also did a dry run with a test case and it worked fine.\n* Then he asked me a problem related to sparse matrix multiplication. I gave him the apporach and wrote the code within time. He was looking fine with that.\n\nRound 4 (Behavioral)\n* Common questions like handle conflicts with manager and peers. \n* Handle negative feedbacks\n* Most prouded project etc.\n\nAs per me, all my rounds went pretty well except System Design round. \n\nFrom recruiter, I got the update that system design and Round 3(Coding) feedback are not positive. I really not sure what went wrong in my Round 3(Coding). Not even a single mistake i made in my coding round.\n\nAnyways, I learned a lot of things in my journey and finally able to crack Uber for SDE3 position. I will share my Uber experience in a separate post. \n\nThanks Again.
