Since 1 month and a half I've started a new job. Since 2 weeks a new colleague joined as well, and the future plan for us is to work together more often (but on different things).
We have already spent some time together, and I have noticed that he definitely had the wrong approach so far. Actually, the time I spent with him has been time wasted. I understand that starting a new job isn't easy, but I believe that he has a wrong idea on how to approach and solve problems in general. I actually believe that he needs someone guiding him day by day. This contradicts his "senior role", for which he has some big tasks, like re-architecturing some internal software.
The 2 senior colleagues sitting next to me (who have worked for 10+ years in this company) seem to think the same. They didn't say it explicitly, but they started with some comments after this new colleague left our desks. Also, they spent quite some time together with me explaining to this new colleague why his approach was wrong (while he was quite adamant about it...).
I'm worried about the future, when I will have to work very often with him, i.e. I will depend on him (and the other way around).
I report directly to the director of engineering, while this other colleague reports to someone else who in turns reports to the director.
I will have soon a 1-on-1 meeting with the director: should I tell him about this new colleague?
If I had more experience in this company, I would have no problem in doing so. However, I'm quite new, although according to other senior colleagues my performance is going very well.
Note that he is in a 1 month trial period, and in 2 weeks he will have to be confirmed (or not).
Also note that, although similar, this situation is not covered by other questions on this site. Indeed, I'm new, and the colleague I'm talking about is even newer. It is not about reporting a senior colleague.
