Corvus Robotics interview questions

Awkward interview with very informal offer letter. Start up vibes are real. CEO does not have the experience needed to perform interviews and make candidates feel welcome. CEO does not give the feeling of confidence in the company. Called me on a weekend to ask more questions. When you decline initially, you may get a panic call offering you a higher salary, or a different pay structure. Health insurance offer is very strange and a lot of clarification was needed regarding all benefits. I was told when I "should" use my PTO instead of told how the PTO system works. Overall a very pushy process that ultimately did not give me confidence in working at this company.
