      SDE-2 Backend Interview

      Negative experience
      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at Trell in Jun 2021

      Interview

      Round 1 - Exploratory Round -Brief discussion about background, culture fit and current company projects, tech stack, service architecture etc Round 2 - Problem Solving and Computer Science Questions - Conducted by InterviewVector - DSA problems, general CS questions Round 3 - Problem Solving Round 2 - DSA Problems - Was asked a problem with overlapping subproblems, - Interviewer sounded condescending. The standard way of approaching such problems is recursion solution -> memoization -> dynamic programming. - Although I was on the right track. Interviewer expected people to spit out the most optimal DP solution in first shot. Was able to solve using memoization and then time got over. After the 3 rounds that went well I was ghosted. No updates on the process. Company lacks professionalism, not recommended.
