KLA-Tencor's hiring process is pretty fast.

1. Applied through Naukri (Day 1)
2. Call for Telephonic Round (Day 2)
3. Telephonic Interview (Day 3)
4. Same Day Confirmation of result of Telephonic Interview & F2F scheduling (Day 3)

7. Confirmation regarding final selection and Negotiation very next day (Day 9)
8. Offer Prepared and waiting for approval & receipt (Day 10)

It was really a pretty fast procedure unlike my current employer where process started on January and offered in September.

Interview Process :

1. Telephonic Technical Discussion
2. F2F Written Test : 1 hr
3. F2F Aptitude Test : 30 mins
4. F2F Logical Reasoning : 30 mins
5. F2F Technical Discussion : 1 hr
6. F2F Technical Discussion : 1 hr
7. F2F Managerial Discussion : 1 hr
8. F2F HR Discussion : 30 mins
9. Skpye Video Chat with Site President : Technical, Managerial, Behavioral Discussion : 1.5 hrs

Once I reached to office in Chennai, HR informed me the Process and I was wondering on "Written Test" for 9+ years of Exp candidate, amazing.

I didn't find any very difficult question but unexpected things :

1. Written test for mid career candidate
2. Site president asking very technical questions
