Some of the main things I've noticed: - Lazily using "full-stack development" for every position as a means of avoiding the hard work of actually managing people, providing meaningful job descriptions, and respecting specialties. A company with a huge army of undifferentiated full-stack positions is a major red flag. - Unwillingness to negotiate regarding private offices or remote / work from home options for people who are not compatible with the noise & productivity loss caused by open-plan offices. - Hyper focus on your salary expectations early in the process without reciprocal willingness to share the budgeted salary range. This extends to hyper focus on relocation costs or other compensation items too. - Jobs that don't provide relocation. Sometimes there are good reasons, but many times it's because of cliquish culture and/or extreme cheapness. - Paternalism: does the management act like your vacation time, your pay, other forms of compensation, or other perks are "generous gifts" doled out by the company? Do they act like the company "is a family" and have weird workplace cultural norms about key management "principles"? - Are all of the recent Glassdoor reviews 5-stars with unrealistically glowing reviews that sound like they were written by a PR firm, and all of the bad reviews are buried at the end and sound like what an actual human would write? - Any unreasonable demands for access to private data about you, such as statements about past income or addresses, test results for things like IQ or personality tests. I agree with other comments that even asking for test results is a bad sign, but even if the test results were legitimately useful for hiring (they aren't), there's still the issue of distrusting some random company with private data about you, or being skeptical of their network security. - If anyone tries to talk you out of your financial requirements with lame excuses, it's a red flag. For example, when I've countered lowball offers before, I've had HR reps debate with me exactly which apartment buildings and locations nearby I could live in at the wage they countered with. Anybody prying into your private life like that ("hey I know where you should choose to afford to live") is nuts, and you should run away.
