GetMyParking Interview Experience - SSE role 3-5 yrs exp (Result - Not selected)

Recently, i gave the interview for Senior Software Engineer role.
Got a call from naukri.com and got an interview scheduled for tuesday 1-2pm
The interviewer came late and interview started at 1:30pm . He asked an easy leetcode question Remove duplicate elements in a sorted array in-place. Solved it easily, was given a black google docs to solve it.
Then he asked conceptual questions, also asked to share about the most challenging problem that i faced in my recent rexperience. Asked an LLD type question based on payments, to return a list of transactions with failed status and pending with TTL expired. I solved it roughly but maybe the interviewer was not satisfied. The interview went for an hour and half.
