KAYAK interview questions

The recruiter sent me a take-home assignment and require me to finish it within 5 business days. There is no introduction call or other interactions. After I finish the assignment, the recruiter became ghosted and never heard any updates. It seems they are not going to proceed the hiring process. Those assignments are like been sent by bots.

It was a very quick process and they were quite responsive with giving feedback. The questions were relevant and they made me feel comfortable during the interview. I had only 2 stages of interviews
