Corephotonics Software Engineer interview questions

The technical and HR interviews were a positive experience, but when I reached the final stage of an interview with the CEO and CTO, I got the impression that they didn't want to interview me, and that they were in a hurry to get it over with. COVID-related information: The company doesn't believe in a work from home option, and everyone (which is mostly developers) works fully from the office. Some workers, including the CEO, don't wear masks.
