The most unethical, uncomfortable and least professional company you'll see. its a red flag and reflects how the company is poorly behaving without an appropriate recruiting system. I applied online and got an email from one of the team there for an interview. First interview is just explanation of what previous work I've done . Then they send you a big task to solve, answer the questions and write in a presentation. It took 9 days to complete. After doing the presentation for 10 people in the online meeting. They didn't give feedback and after 2 weeks when I asked for feedback they said we found someone with better experience.
