MuleSoft Performance Engineer interview questions

First, I had a phone screen with the recruiter, then I did a technical phone interview with group tech lead. Phone interview questions are performance area related, then followed with a coding question. Everything went well and I had onsite interview with 4 people at SF office (3 in person and one phone call). First round is a ~2hr (or 90 mins, I don't remember) pair programming excise, the problem is not performance area specific, but the difficulty is medium level, but with corner cases. The engineer who did pair programming with me was patient and professional, just like my co-worker! Other three interviews are a mix of technical and behavior questions. In general, my interview experience is great, the interviewees are nice and my interview experience is great. Last but not the least, my recruiter is very professional and helpful, he accommodates my schedule for phone calls since I am in a different time zone, and he always provides updates about my interview progress, and he helped me get an offer approved in a short amount of time.
