I have a very junior colleague sitting to my right, he graduated 5 months ago and this is his first job, he works in a different team. I have been working for 10+ years. He is otherwise quite fine, friendly and all. But a lot of times he acts his age, which is very immature and unprofessional. Below are some examples from this week alone-
- One day, my boss came and told me - "wow, you were working late last night and today morning also you are early". At this moment, out of no where, he barges in and says "he was not here when I came, so I know he didn't sleep here". Basically trying to make a point that he came in earlier than me, even though it was not his boss. Completely stealing my moment.
- Then y'day I was discussing some project with my boss and we just happen to mention my colleague's team's name. He literally sprang form his chair, walked over to us and said "what are you discussing". I was trying to nudge the conversation to a particular direction and he totally ruined it. And it was not even related to him. We cant really be expected to walk off to a room for every other thing that we have to talk about.
- A lot of times if anyone has asked me something (nothing private/confidential/worthy of a separate meeting), god forbid, if he has heard the question he must answer it. He does not care that the question was not even addressed to him!No body likes being interrupted and given how frequently he does it, it annoys me even more.
Such incidents happen pretty much every other day. From what I know about him, he is not an evil person. But he still ends up acting like one and seriously irritating me.
I need some help/tips on how to change his behavior without really making him feel bad. Is there something I could do or say (how would I put it?). I have tried completely ignoring him for few hours when he behaves like this but his immaturity prevents him from getting the message.
