Oktas interview process was one of the smoothest that I have seen thus far. The recruiter was very responsive and accommodative. I had a phone screening with the recruiter first where she asked me some basic Java related questions. I spoke later to a senior engineer who gave me a coding question on coderpad to find the nth largest element in a list. I was then called onsite to their SF office for a day long session with around 10 interviewers. Most interviews had shadow interviewers as well, so I had about 7 interviews onsite. The recruiter promptly called me on the next day to inform that my skill set did not exactly match their requirements.
