I applied online. I interviewed at Trailstone (London, England) in Dec 2022
Interview
Went through three rounds - first two were friendly and not particularly technical, discussed projects and coding experience. Final round was with multiple people and involved very technical questions about Python implementation which I failed to answer - would have preferred a live coding challenge to just verbally answering theoretical questions.

I applied online. The process took 2 weeks. I interviewed at Trailstone (Austin, TX) in Jan 2021
Interview
The process was 2 standard HR phone interviews followed by a phone call with an engineering manager where I was asked to discuss the technical aspects of my experience. The final interview was a panel style with two engineers and the CTO. I was asked technical questions regarding bullets on my resume and other questions to gauge my thought process when solving typical software bugs.
