Agreed. I've worked for people that are like that. I never took it personally. Because they never attacked me personally. However, I will say that one trick I've learned over the years is to "frame the questions" as though you're both on the same side of the dialogue. You're both fighting against the thing on the other side of the table, which is the functionality / app you're creating. If you can frame questions in that way, to ensure people don't feel they're on the receiving end of personal attacks, this is invaluable and makes it easier for people to accept those "pointed questions" as valid criticism, and helps them realize that you're asking the questions only because of your undying desire to get things right. It keeps people from feeling under attack when anything they're working on gets questioned / interrogated. While many times people think the boss always thinks they're right, generally those people are just more timid than the average person I think. If they opened up and disagreed or questioned parts of the interrogation they would realize the questioner is only opening a dialogue, not establishing that they're always going to be right and that the person needs to "fall in line".
