Questions posées lors d’un entretien d’embauche pour Senior Python Developer/Software Engineer chez Entain India

Negative experience. Easy Questions. No feedback for rejection. Seems more of a budget issue. I applied via referral, received a call from HR in 4 days. Interview round 1 was all about Python and MySQL basics, which I managed to clear comfortably. Got a call from HR the same day that I made it to round 2 Round 2 was a mix of OOP, Sorting and DS/Algo questions, which I answered. After constantly following up for 7 days, HR sends a mail stating that I'm rejected. No appropriate reason for the same. Moreover, in both the rounds, the interviewer came late by 15 mins that too after me sending an email to them about the technical interview reminder. No punctuality and no professionalism, yet they call themselves a product based company.
