Usually three steps: first with a duo of junior team members that will evaluate you based on cultural fit mostly, as well as for the mindset you have. If you make it past the first interview, you'll be an interview with Chris Out, RockBoost founder. This is a very difficult interview, and it could be over in under five minutes (or it could last an hour). He is very quick to size someone up. If you make it past this interview, you're 90% of the way there. The last step is an interview with Chris and the other managing partners of RockBoost. If they all agree, then you're in.
