10bis Full Stack Developer interview questions

I was approached by a recruiter working directly for the company. * I had a short phone session with the recruiter. * Later a video session with 2 team / group leaders. They were not clear on what they wanted for the role. After the video session they gave no response and after a while (2-3 weeks) I said that unless I receive a response within a day I will withdraw from the process, as I prefer to keep ongoing processes to a minimum. They got back a day later and said I was rejected. No explanation. No feedback. When I asked to inspect my personal data, with regards to the interview process I learned they use some candidate application software. They sent back a screenshot showing virtually nothing but the basic details. The phone interview and video session were basically blanks. Knowing Israeli companies I rather doubt that nothing was actually written. It took them about 3 weeks to send that screenshot. Which is an unusually long period of time to take a simple screenshot. Most people I know of can perform that task in a matter of minutes. I suspect there was some information which they deleted / kept hidden. Another explanation is they just waited for 2-3 weeks or so before telling me I was rejected, for no apparent reason. I would suggest other candidates to stay away from such companies. They obviously have no respect for candidate's time and effort.
