Okay. So I would suggest not to waste your time in the interview process with Apollo.io. I feel they are not interested in hiring good folks. I was interviewed for a Senior QA role, and the first exploratory round went pretty well. I answered all the questions, even more than was expected from a Lead QA engineer, and the interviewer looked pretty convinced too. But I'm not sure why I was rejected. Maybe he might be insecure.

Basics of framework, testing strategy, work experience, team challenges and how you solve them, non-functional testing, debugging skills, Elasticsearch, AWS, etc.
