I was contacted by HR of this company through Linkedin. She had initial call with me for around 20min where she explained the position etc and asked me few technical questions (yes HR asked me tech questions). And the question were pretty simple, bitwise and logical OR, object model for vehicle which can be a car or a bike. After the first call I was setup for another phone interview with the hiring manager. This call was for an hour and I was asked algorithmic questions. One of the questions was about a file with strings in it which are sorted and to create a data structure to search the word when 4 letters of the word is typed. The interviewer was pretty easy going and was not looking for exact solution. Instead he was more interested in the approach. And then I was setup to talk to another engineering member on the phone for 45min. This one went well too. He asked just 1 question. And the problem was to find the first repeating letter in a string. i.e "abcdaer" is a given string so tell the position of first repeating letter that is 'a'. This interview went well too. But I did not hear back from them. So, I sent an email to the HR to know the result. She replied to the email and thanked for reminding her :-). Well, this whole process till now took 1 week. And then I was called for in-person interview the following week. I went to their office and HR received me at front desk. She took me to a conference room and little bit later informed me that the first interview is with an engineer instead of hiring manager as per the schedule. The first engineer walks into the room, introduces himself and without any further talk gives me a laptop and asks me to implement priority queue using the language of my choice. It was little odd as usually people start by talking about experience etc. But anyway, I tried implementing it but running it was a bit of a challenge as collabedit does not support it. After an hour next engineer came who asked me 10 different questions. Minessweeper, inner join, outer join, code to return true if in a string parentheses are closed (or valid) i.e "()()" is valid and return false if parentheses are not closed i.e. "((()" is invalid. It was almost an hour interview but then the hiring manager asked the interviewer to come out (he did not walk into the room, made some gestures for the engineer to come out through the glass wall). then HR came in the room to tell me that the team thought I was not a good fit. I found the in-person interview process pretty unfriendly and sorta rude.

I was contacted through LinkedIn by the manager of one of the teams. I was asked if I am interested in position after sharing the job description with me. Later a phone screening round was set where I was asked questions related projects on my resume. Got a mail from HR for the second round which was onsite. HR was very welcoming, gave a quick tour of the office. Later I was interviewed by two people. This interview was not so tough.
