My first interview with TDX was facilitated by the coding bootcamp I was attending at the time (Tech Elevator). It was a short panel interview with the three team leads of the engineering department. It was mostly focused on getting to know each other with a few basic competency questions mixed in. From there I was brought in for a three hour on-site interview. It was broken up into three parts. Each part was spent with a different team lead and consisted of entirely different questions. The first hour was almost all technical and included working through a kata on the whiteboard. The second hour consisted of creative questions designed to test how you think. No matter how much prep you do before hand some of these questions will be surprise you. The third hour was a one on one with the director of engineering and consisted of behavioral questions and an opportunity to ask questions about the company. It was an intense process, but very well designed. It gave me the opportunity to demonstrate my knowledge and how I approach problems while also giving me a great intro to the company and the team leads. Also, TDX was very quick to get back to me after my on-site interview which I really appreciated since I was interviewing with multiple companies.
