RTX interview questions

1 full day on-site interview. 1-hour presentation, technical Qs. Lunch 1 hour with the project manager 1 hour with the team with the site Director lots of Qs, people were friendly. but got no reply after the interview. contacted HR several times but the hiring manager refused to reply. so at the end, I got no response. very disappointing.

Asked basic OOD principals and to describe them. 2 Rounds of interviews, none were technical. Received offer in four weeks. Process was pretty quick. Was also given an overview of the process and the position.
