Red flags before even interviewing: (1) Below average salary for a principal level (2) Use ClearCompany for an ATS, which has the worst UX. Both are signs not much value is placed on applicants/employees. Phone screen was very standard. More red flags — many offshore engineers (a sign cost is more important than quality). Backfill for someone who left (drama). Few days later got a passive-aggressive rejection email. Said not enough questions about the business itself or the problem it is trying to solve. NEWSFLASH. Initial phone screens are SUPPOSED to handle logistical questions. In-depth business problems and strategy discussions are more appropriate for the hiring manager at the next stage. At least it was honest feedback and not a boilerplate rejection email.
