First round consisted of a recruiter call. Second was speaking with the hiring manager. Two more conversations with members of the hiring manager's team. Final round was a presentation on the solution.

From my first call with the recruiter to receiving an offer, the interview process spanned a little over two months. It involved two recruiter calls (there was a change in recruiter), two behavioral interviews with a manager and later an executive, and a technical challenge and presentation. The preparation for the challenge was time consuming but helped me to understand the company product better. Overall, the process was smooth albeit lengthy.
