When they said that they are tech agnostic when it comes to hiring - they mean it! I really was impressed with the overall interview process as I was in middle of interviewing with other companies and had a tight deadline to accept an offer, Prezzee accelerated the process for me, so instead of days and weeks spending to know if I had progressed on the next stage, I was informed and taken through all the stages quite quickly. The offer was made very promptly as well understanding my situation. The questions were definitely around what my experience was and my ability to solve a problem and not around languages or code.
