Interview Preparation Tips

Interview preparation tips for other job seekers - They took my resume from Naukri and contacted me, and 1st round of interview was scheduled. Questions were mostly based on projects in the resume, basics of machine learning, statistics, and hypothesis testing.
The recruiter said that you are selected for 2nd round and this will be with the Vice president.
That vice president did not have any time sense and the interview was scheduled at 10:30 in the night and he joined at 10:45, he started asking about the projects which was done 4 years ago(which was not stall mentioned in the resume). Later started asking about the current project.

Then he asked how did you do hyperparameter tuning, I said using GridSearchCV, he asked did you not use scikit-learn?. He does not even know that GridSerachCv is one of the class inside scikit-learn.

Later I contacted recruiter, she started ignoring my calls, after trying for 5 times, I asked did you get any feedback,? she said still I have not got. How much time they want to say if I am selected for the next round or rejected? I said even if I am not selected, please inform me. But still she has not said anything.
