Questions asked were not very structured. Process is stressful. The interviewers are friendly and give good overview of the company and role they are hiring for. Some technical questions are very difficult and I am required to give a presentation on the spot without any preparation.

Standard practice and process. Initial onsite interview with a few people - lead developer, junior developer, and a project manager. Basic technical questions. We discussed tech debt, and software engineering concepts. There was a bit of white-boarding on cloud concepts and using message queues. Companies these days seem so excited on this /new/ concept. Whenever I tell them this message pump concept has existed in Windows since before 3.1, they seem stunned and that every windows engineer has been using these ideas for years and years. I was invited back the following week for a second interview with a different panel. The senior dev's were not sure where to start and how to ask interview questions. Totally under prepared. I tried to ask them open ended questions such as their most used design patterns, but these questions were lost on them. I followed up with a few emails, but there was no formal reply or feedback. This was the most disappointing. Seemed like an OK company to be employed with a range of energy projects.
