I spoke to recruiter. Later she asked me about my schedule for screening round. She mentioned one screening round and then onsite. First zoom interview interviewer asked me to write a small program and completed with out optimization. Later he asked me to optimize it. I wrote a code but it has small and didn't work as expected. He mentioned your approach is wrong :). I found a bug and fixed it. It is working as expected. He is happy with that. Next day recruiter contacted me asked about my schedule for another screening round. I asked her why again screening round. She said we have two screenings then onsite. I was talking about my experience interviewer interrupted me and told me know all about these companies. Seems he doesn't like to know my experience. Then he asked me a coding question, actually he knows only answer and seems like he feels every problem has only one solution :). I explained my answer but he still doesn't understand my answer. Still he supports his solution only. He asked me to share my screen. Very bad interviewer. Lost my interest in this interviewer.
