First I did and interview with their IT Specialist recruiter phone call which was very smooth, he asked some couple of basic question and at the end of the day he asked me if i want to ask him any question next I had skype interview with An IT manager which was smooth also

Overall, everyone was friendly and helpful during the interview process. However, after the onsite interview, I was ghosted for 2 weeks. After that they just sent me a super short and generic rejection email with no feedback or details about why they got that decision. I would've appreciated some feedback, if any at all, after going through all the interview stages and meeting with so many people from the company.
