ecobee Embedded Developer interview questions

I had 2 interviews with a VP and a Director. A third meeting was supposed to be a presentation for a case-study about implementing a Railway simulator. I was supposed to present my project in 30 minutes and have a Q & A for another 30 minutes. A particular Staff member started interrupting my presentation just after 5 minutes of its start and kept interrupting me all the way long. He also asked me to skip some demo features even withing my 30 minutes presentation time. Despite the job was for embedded system their case-study was probably 95% UI development and 5% the actual simulation coding. I decided to implement the 95% in C++ and I created an embedded python interpreter to isolate and facilitate the simulation coding. At the end I was disqualified for the position as my code-base was "too big" and "complex" for them to review. So you are asked to implement "A". You deliver "A" + "B". Anywhere in the world you are considered to exceed the expectations. But at Ecobee you are a failure. They are either really narrow minded or they gaslights you by fabricating reasons to kick you out. I will never ever apply to this company again. BTW... my case-study is at github, search for tracksim under user mvaranda. Video demos are in the readme (or just scroll down). Think twice before wasting your time with this company.

fast and straightforward. First, I had a 30 minute phone interview with HR. Then an hour online meeting with the hiring manager. I was rejected, but they provided valuable feedback.
