Application

I applied through a recruiter. The process took 4 weeks. I interviewed at Critical Mass in Aug 2021

Interview

The steps were clear. Started off with a 30 minute screening call, followed with a coding challenge which included creating a website and make a readme with answers of the questions asked. And then the last round was a 30 minute interview with Technology Director. Received an automated rejection email after 3 days with no feedback and even the recruiter didn't replied to any emails for feedback.
