TLDR : A pretty much weird/bad experience with Salesforce India interview. Don't waste your time with them if you are willing to do so. So I was contacted by one of the recruiters for SF India office. The first round was coding round. There were two interviewers. After a brief chit chat we started for the 'coding' part. First question was to reverse an integer. Well, to say the least I am pretty much decent in problem solving so it took hardly 2-3 minutes to tell the approach and solve it (with all the proper handling of the negative numbers, overflow cases etc). Next question was to find the first and last occurrence of a number in a sorted array. Which again I solved using binary search with a pretty much in depth discussion regarding the approach and tradeoffs! The other interviewer was pretty much a silent spectator and the one interviewer who was discussing the solution was pretty much convinced with the solution and optimizations. Then, after half an hour I got a call from the recruiter saying, "Your coding round didn't go well. Your coding skills were not up-to mark. There were lots of errors. Code wasn't optimized". I mean what the actual hell! At this point I am not even able to comprehend what did the interviewer want from this round. What are the expectations? To code binary search and reverse an integer in assembly language or use punch cards? At least set straight your expectation so that I am ready with some assembly language, may be? Seriously, this was the most weird experience I ever had! To anyone who is willing to spare some time to interview here, please don't! I am not sure about other centers, but this experience in India location did really leave a bitter taste. 10/10 won't recommend to any one!
