SciSpace Software Development Engineer SDE II interview questions

The process took a couple of weeks. I was approached by the recruiting agency. Initially, there was supposed to be a screening round, which got re-scheduled 3 times. The interviewer ghosted both times and didn't even bother to inform me that he would not be joining. I had to follow up constantly with the recruiting agency's HR for updates and re-scheduling. After the screening round, again there were no updates and I had to follow up with the agency only to find out later verbally from the HR that my profile would not be selected. No email communication at all! Upon asking for a reason, the company didn't mention any to HR. The HR managed to convince the team for further rounds but I refused to proceed further. Waste of time and energy. Very unprofessional. DO NOT WASTE YOUR TIME WITH THIS COMPANY. NOT WORTH IT!
