Camunda Front-End Developer interview questions

The interview process is quite long and you receive a flow chart describing the whole process. I started by doing a coding test, which I passed and then went on to have a phone call to discuss previous experience and respond to some simple technical questions were made. Even though I thought it went pretty well I was rejected. Most interestingly the flowchart which they had sent me in the beginning of the process, got an almost immediate status update after this interview to 'Rejected' but I only received a rejection email 3 days later. Since I was curious to understand what went wrong I wrote back, but received no response whatsoever.

The company will send you a flow-chart about their hiring process. For the position I applied, the process involves first a coding challenge, then a video call, and 2 on-site interviews.
