Four interviews. First HR interview then two technical interviews. Last interview is at SE facility long with tour. SE realy takes your work interests into the account and mark clear expectations.

Got a call for interview drive on Saturday. 2 tech rounds, one Managerial round held on their interview drive followed by a tech discussion with the director and finally HR interview. It was a smooth process. Especially meeting the director and discussion with him on technical aspects was new for me.
