Almost every place I’ve worked I’ve had to deal with people as you describe. If you want to advance you need to develop strategies to deal with disruption. Depending on the situation you could; explain you are trying to learn a specific topic and ask them for their experienced insights (a little flattery never hurts and they might share helpful information), enforce your boundaries and say the question is a bit personal and makes you uncomfortable, say the day has you frazzled and you need quiet time to concentrate/regroup (again maybe flattery, I don’t know how you are so calm on a day like today), redirect the question back on them (you don’t actually have to care and listen, just some fake active listening nodding, say really, wow and make some eye contact), occasionally give some tidbits to appease them and not appear too stand-off ish, could be real or just make shit up) Consider what Jordanlund said, it might be their way of dealing with pressure, be more understanding, everyone has different coping mechanisms. Also tell yourself the situation is temporary, it is a stepping stone to your next goal and you will not have to deal with them forever.
