Totally agree. The author did not even approach the possibility that their questions would count against them in an interview. You have to tread very carefully with these kinds of questions. It can be a great opportunity to share mutual pain point experiences with the interviewer which enhances your perceived experience. You don’t want to come off as the guy whose going to rock the boat never having been in it in the first place. At most, I want to gauge the potential for change rather than the tech stack status quo.
