First meeting was with a recruiter. Seemed really nice, explained the company pretty well. I felt really good about interviewing with the company. I would say by the end of all 7 challenges, you would have to meet the criteria of about 50ish+ tests...I don't know, i got bored, closed qualified.io and emailed them to say I wasn't interested. The coding challenge was kind of a leetcode hack, where they will just turn you down without talking to you after you spend hours working on the coding challenge. To be honest, the band for this job should be higher if they want senior devs to go revisit DSA's for a job that will not require them.
