they are looking specifically postgresql. second round a person called john was asking to write codes . they are supporting some usa clients . company located near infosys office as per google..

Worst interview experience. They asked me "Are you from Tamilnadu?", I said no, he was like you look like tamilian , then he asked do you speak tamil? Really?? Is it the way to start any interview.. They don't deserve to be in Bengaluru or in IT industry? Please Folks never ever go for an interview.. its just waste of time.

There are three technical rounds. First is a written round. The questions were very basic - questions about classes/OO, data structures like trees/queues/stacks etc. Once the written round is done you are given a computer and given a program to solve. The program itself is trivial to implement. You are essentially given any amount of time that you need so take care to write clean efficient well documented code. Once you are done you are expected to run the program with different inputs to ensure that it works well. Third round of technical interview is coding on a computer as well. Compared to second round, this one is a little more involved. This round essentially evaluates how well you design your code. So take care to break down the logic into appropriate classes etc
