First two technical telephone interviews. Then requested for one day onsite interview at Sunnyvale office. I said I can not make it one day instead I will make it come times. HR agreed and scheduled first onsite interview. It was basic project related questions and DS and algorithm questions on white board. I cleared the round and HR updated next day it went well and want to schedule next round after one week.
I attended again onsite interview and was same project related questions and DS on white board. All technical rounds went very well and I am able to answer in first attempt on white board. I did not hear any update for three weeks. I follow up with HR couple of times one time they responded saying they are interviewing other candidates also.
After one month and couple followups I got update team has decided to move forward with another candidate. HR is very irresponsible never respond to any email. Waste of time attending interview here. I never recommend any friends for this company
