Coolblue Junior Data Developer interview questions

Applied online, interviews were at the office. Although the first interview went well, the second was a case presentation for which I had to answer various technically challenging questions. With some help, I managed to answer all of the questions and submitted a good presentation. Soon after, I was called with the facts that my technical knowledge was lacking for this specific function. Although that was the case, they were interested in me at another function (Business Analyst). I would be contacted about the further procedure. For 3 months and counting, I have had no communication with the recruiter responsible for the job offering. Although I tried contacting him multiple (i.e. 5+) times via different channeles, I never got a reply. TL;DR: Although the interview process seems OK, they do not handle replies in a proper and just manner. It might me that specific recruiter though.
