I applied through a recruiter. The process took 4 weeks.
The interview process was long and exhausting. I had a screening and then 4 technical interviews. But, they were very nice people overall and seemed genuinely interested in creating a good experience for the candidate.
However, from my perspective, they seemed to be focused on the wrong things and some of their interviewers' style is disingenuous and cold-faced.
