Capgemini Engineering Python Developer interview questions

Interviewer asked me many data structure questions and just provided me a scenario to solve the question and did not wanted to know the approach I should have take they didn't wanted to discuss on that he just wanted a code to written and the result. they were only concerned with how do you write the code and how long it will take and they would not discuss on the approach.

Interview Process was of 3 rounds: 1) technical face to face 2) technical face to face 3) hiring manager 4) hr round all rounds were cleared. after completion of all rounds hr told me she will get back to me and still after weeks she gave no update and even stop responding to my mails and calls. Very unprofessional behaviour by the HR .
