A job consultant contacted me about a fortnight ago from my first interview. Then I got a call directly from KLA Tencor HR and my interview was scheduled very next day.

The first interview was taken by my future manager. He introduced himself first and told me about the job role even before beginning the interview. It was technical interview where he has asked a couple of C++ questions with moderate difficulty level. He explained about the work and product on which I was supposed to work. He asked couple of maths questions. Like, how you will transform some co-ordinates in a different co-ordinate system.

Second interview was a design interview which was taken by a panel. In which they have given me a situation and asked out to come out with a OO design. It was very open ended.

Third round was with KLA-Tencor India president, where he has asked about my previous projects and likes. Then one more open ended design question was asked to me which I have answered well. It was not on the same day. It was after 3 days from the first interview.

The final interview was with HR where he discussed the salary expectation. He also cross checked how much clear I was on the job role. He clarified roles and responsibilities well.

I was offered a job in 2 days time after HR interview. They sent me the salary breakup first. I was very happy initially to hear the figure that it was decent 65% hike but basepay hike was just 25%. There was a lot of variable component.

Yeah one important thing you should clear out from the manager is the technology stack on which you are going to work on. Because they might interview you in C++, but you may be working with altogether different technology like C# or Java. They have all three C++, C# and Java requirement here. So be clear about that before taking up the offer.

A satellite is going around Earth taking a continuous picture of area 1 meter wide. How would you design and develop a system to build a Google Map sort of application.

A girl and boy is walking in a park and boy is telling the girl about his upcoming on-site trip. He is doing planning about his trip and at the same time discussing the her plans with the girl and walking in part. How you will design this?
