Waiting for feedback, there is strong focus on system design, since coding is improved and achievable by lot of candidates now a days with leetcode help.

The interviewer was not able to understand recurrsive approaches and trying to push me to write code in iterative, be strong with ur approach and to test with diff exaples during interview. For Sr position only 15 min is given for coding in optimised approaches.

A loy of interview expereinces helped , me this my first interview post shared, keep rocking, i was very weak at algos and coding, but 30 days dedicated practice gave me confidance, i dont know i may or may not recieve offer, but i have no fear now. Thanks
