      Software Engineer Interview

      21 Feb 2016
      Anonymous interview candidate
      Bengaluru
      No offer
      Negative experience
      Average interview

      Application

      I applied through a staffing agency. The process took 2 weeks. I interviewed at BT Group (Bengaluru) in Feb 2016

      Interview

      First Round: Written Test (Java+Aptitude--> 55 minutes with negative marking) Second round: Was scheduled at 10 am but due to lack of some resources it actually started at 12.00 noon. F2F interview with one of the most rude persons who feels he is "FATHER OF COMPUTER SCIENCE". Don't even give enough time to solve a question(leave pointing towards the clues). Gave a couple of puzzles to solve(Shape cut puzzle, Divide a square into 7 equal parts and calculation of number of squares in chess board). Interviewer (busy on his SMARTPHONE) didn't even bother to see the solutions. Implement a Singleton class with cloning of the object not allowed. I gave the solution of throwing a CloneNotSupportedException. He told give me other way. He then asked me Cyclomatic complexity. I told the answer and added that It will be tough to maintain and debug if the cyclomatic complexity is high. Also added that compiler branch prediction algorithm also will suffer as nested branches increase. Then the interview replied saying "Being a programmer why should I think about the COMPILER" which was most insane part of an interview. I was really shocked/ashamed to hear this comment fro such a senior guy. I now stared feeling that it was big mistake attending this sort of interview Told me to write Binary Search and suddenly told not to write the same. Continued saying that a couple of guys from my previous company did join and left his team in a duration of months. So, he told that he didn't want the guys with kind of skills that matched my skills(Android and Java). I was shocked to hear this. Then why was I shortlisted? Already, they had my resume during the written test itself. I don't recommend this company to anyone. They don't respect time of candidates and their skills. They respect only their own-self-attitude and their own technical skills.

      Interview questions [1]

      Question 1

      Explain Software Cyclomatic compexity. Explain Singleton Pattern. Explain how does the query from browser fetches the result from remote location.
