Perion Network Developer Student Position interview questions

It was a recruiting day. They brought about 30 peaople at the same time. First they presented the company and the team and the the head of the HR presented the social asspect of the company. It was not clear for what exact position you are interviewed for and in my opinion there were too many people. They gave us all a test and we took it all together in the same room which made it difficult to concentrate. The process was in overall a bad expirience. In my opinion they were trying to save time and money on the recruiting process but it was disrespectful and damaging to us.
