Previous Position - Software Engineer II\nPrevious Organisation - Sabre\nLocation - Bengaluru, India\nYears of Experience - 1.5 years of Experience\n\nApplied through referral.\n\n**Telephonic Conversation with HR (5-10 mins)**\n\nHR asked few questions about the current organization - CTC drawn, tech stack, reason for switch etc.\nHe told that according to their company standards my years of experience was lesser for SDE-2 So, whether I\'ll be fine to go for SDE-1 role. I agreed on it.\n\nHR explained interview process - 3 Technical Rounds\n- Technical Round 1 - Bar Raiser (3rd party)\n- Technical Round 2 - Coding\n- Technical Round 3 - LLD\n\nI asked HR about bar raiser round - So, he said it will revolve around the DSA and CS fundamentals.\n\n**Technical Round-1 (Bar Raiser): (1.5 hr)**\n\nInterviewer was a senior developer with 8 YOE.\n- He started explaining the process of interview.\n- He said he\'ll ask 1 DSA problem and 1 Design problem giving 45 mins to each.\n- I was bit surprised by design problem as it was not expected in this round.\n- Then, he went straight to problem solving and asked to solve it on my IDE from scratch.\n\nProblem (LC- Medium) : https://leetcode.com/problems/merge-intervals/description/\n- He explained the problem to me and gave me sometime to think for the approach.\n- I explained him my approach first and started coding the solution.\n- After coding the solution, he said to run it with some sample inputs.\n- The solution gave correct output.\n- So, he asked me about the time and space complexity analysis of the solution.\n\nAfter this, he jumped to designing problem - Design Cab booking service similar to OLA/Uber.\n- He said that he is more interested in the API designs and DB designs. He was not looking for any coding solution for it.\n- He started giving me some API examples to incorporate.\n- I explained him all the flow and designed all the API\n- At last we discussed about the DB Schema.\n- Reason to choose SQL data base and discussion on ACID properties.\n\nWe could finish the interview at exact 1.5 hr. Interviewer was very kind person and gave ample amount of time to think and come up with solution.\n\n**Technical Round-2 : (1 hr)**\n\nInterviewer was a SDE 3 in Kotak.\n\n- We had a very in depth discussion on the previous project in the company for around 20-25 mins.\n- He was from Java and Spring background, so he deeped dive in my previous project.\n- There were questions from Microservices, Database, API  etc. \n\nAfter that he started asking questions from JAVA.\n- Implementation of HashMap in Java Collections framework - what is collisions, loading factor etc.\n- How to make a class immutable? - using final keyword\n- Difference between method overloading and overriding?\n- Inheritance\n\nThen he jumped to Problem solving-\nProblem : https://www.geeksforgeeks.org/find-a-peak-in-a-given-array/\n\n- I was asked to code it in my IDE.\n- I gave the solution O(n) time complexity and ran the sample cases.\n- He asked if I could optimize it further.\n- I explained the approach of using binary search and optimizing it to O(log n)\n- But since we were out of time so, he concluded the interview there itself.\n\nI believed my interview went quite well and was expecting being shortlisted for next round. But to my great surprise when I contacted HR next day, it was a reject. \n\nHe didn\'t give me proper feedback and just said that interviewer didn\'t feel your technical skills match expectations for profile\n\nThis was weird as I still can\'t decipher what went wrong in Round-2?
