Negative experience - assuring interviews with recruiter and technical specialist that I am one of the best candidates (during Door3 interview, not a client) and later got refusal and no feedback about reasons, which felt weird after what was said after the interviews, which passed great IMHO.

Great venue! Everytime I’ve been here with my friends, we had the time of our lives. Great vibes and music always. Would highly recommend you check out if you’re looking for a spot on a Friday or Saturday night - you’ll be dancing and singing the night away for sure.
