Larsen & Toubro Jr Engineer interview questions

I interviewed with L&T starting with the aptitude test. The second round was technical, conducted on google meet where a panel of 4-5 interviewers. They asked questions about my thesis project and some basics. The technical round was about 45 mins, after getting shortlisted they scheduled a medical test for me. But unfortunately i don't know the reason why I didn't receive the offer letter after that .
