Questions posées lors d’un entretien d’embauche pour Software Developer (Python) chez J.P. Morgan

The Interview process took around 3-4 weeks, 1st Round was only General Discussion on the Position/Role with the VP of Software engineering in India After Round I : Given a home Assignment on Super Simple Stock Market (you can get it on github easily) to submit in 3-4 days 2nd Round was a technical for 2 hours , but the HR did not told what will be there in that around not even the agenda even after I emailed to get the same info. The 2nd Round was scheduled for friday 5:30 Pm (IST) and then at last moment I was ready for the interview , when i joined the link of meet nobody was available for taking the interview , then i called the HR who scheduled the meet , she told 1 interviewee is not available so it will be postponed. Really very unprofessional behavior from such a big company. Then she told that will rearrange it for next friday. Very strict about the timing for each question /session.
