SPTS Technologies Field Service Engineer (FSE) interview questions

Very thorough interview process consisting of multiple zoom interviews with various members of management including Director level through TPS and a series of challenging questions ranging from written electrical engineering problems and circuit troubleshooting using complex schematics through many behavioral questions. Relentless questions nearing a point of intimidation -they wanted to see if I had a breaking point which caused scheduling of additional complex engineering questions requiring in depth and fundamental troubleshooting methodologies including the use of fish one diagrams etc.
