KLA-Tencor Interview Process


I applied at KLA-Tencor for the post of Senior Software Engineer with the help of a recruiter. The process took some two weeks or more and then I was called for the interview at KLA-Tencor. The hiring process had three technical rounds followed by an HR Interview.

Round 1 - First Technical Interview
The first technical interview started with the basic knowledge and then shifted to more advanced levels. The basic concepts of OOPS were asked and their implementation was asked. A question on the philosophy of OOPS was also asked. There were questions on static keyword, static members and static object. Some other questions:
Q1. Why const key word, const functions and its significance.
Q2. Which data structure is used by compiler to store local variables?

Round 2 - Second Technical Interview
This was more or less the same thing as the previous round. Only they did not start with the basics in this round and focused extensively on the advanced level problems. Some questions around trees were asked and also some questions based on STL and data structures. A couple of algorithms related problems were also given.

Round 3 - Third Technical Interview
This technical round was based majorly on Data Structures and the designing part. I was given about eight scenario based programs for which I had to write pseudo code. They have me a certain scenarios and I was asked to design class for them. Some basic questions related with design patters were asked as well. Some questions on threading, sync objects and search algos were asked too. This interview was pretty long and tiring.

Round 4 - HR Interview
After I was given a green signal in the previous round, I was called for the HR interview. Thankfully, it was just a formality round and I was not asked a whole lot of questions again. The offer was also made in this round and negotiations took place as well. All other aspects were made clear as well. I took the offer.


How to crack (get into) KLA-Tencor Interview


As I have written, there were three long technical rounds especially the last one was so long. Of course I am telling the process for the senior position. If you are a fresher you will definitely be going through an easier process.

So here is the thing. There are no particular pointers I can give you for cracking the KLA-Tencor in general. You have to be ready for extensive range of questions and problems. But yes, they focused much on the data structures and the design part. So you must fore mostly go through that.

The good thing about the interview at KLA-Tencor is that they are trying to hire someone, not reject. So they will be pretty nice with you and may direct you towards the answer many a times if you are performing well. Except for the third technical round, they will also ask you your strong areas and the following questions will be majorly based on that.

The environment at the company is quite good. The interview process was also great. So, prepare hard and try to impress the interviewers. All the best for your interview.
