There are any number of acceptable equivalents. - overqualified based on years of experience. We don’t think they’ll be happy with the simple work we can offer. - low growth potential. If the candidate has been a senior engineer for X years, that’s probably their plateau. - not a “dynamic self-starter” or other euphemisms for “young and dumb enough to send on a high risk mission.” It’d be a particularly clueless manager who can’t say what they mean without getting in trouble.
