Staff Engineer Interview

Anonymous Employee in Sunnyvale, CA
Accepted Offer
Positive Experience
Difficult Interview

Application

I applied through an employee referral. The process took 4 weeks. I interviewed at Infinera (Sunnyvale, CA) in March 2015.

Interview

Though I went thru employee referral but I have given 2 phone interviews, one with Hiring Manage and another one pure technical.

Then they called me for onsite interview where 5 people took 1:1 pure technical on C/C++ concepts, OS concepts and some white board exercise.

After a week I got a call for another onsite interview where I met 4 people 1:1 and pattern was same except there was coding challenge or session.

After a week, I got the offer and was decent one and I did not negotiated as they gave more than what I had asked.

Overall it was nice experience and people are friendly in interview and are giving hints as and when required.

    Application

    I applied through an employee referral. The process took 3 weeks. I interviewed at Infinera (Sunnyvale, CA).

    Interview

    I had the interview through an employee referral so this was faster. The interviews are very detailed take atleast 6 hours plus, but basic questions in programming (c and c++)and basic concepts in OS (sempahores, deadlocks etc). A refresh on these can be easier. Most of the questions are around linked lists, bit operations, string reversal etc. People are quite friendly and make you feel quite comfortable in the interview
