The company I work for has a mandatory mentoring program. Every employee is mentored by his line manager. I have meetings with my mentor every two to three weeks. The idea is to talk about areas I want to improve in and my mentor supports my growth.
However I am discovering that my mentor uses these sessions to learn about my weak spots, and then uses that knowledge to erode my confidence and sabotage my career.
How do I best deal with the situation?
Update: Let me share a concrete example. I work in a technical role on a team of 7 people. As I am the most senior one on the team and I enjoy taking up responsibility I have informally moved in a leadership role within the team. I enjoy sharing my knowledge with my colleagues and making sure they have everything they need to work at their best. Within the team we have a fantastic collaboration and a great spirit. Me and my colleagues are in daily contact, they often contact me to get my input on challenges, and although the project is challenging we often find time for a little chit chat and some jokes. This is something that every member of the team enjoys and frequently mentions in our retrospective meetings. With the upcoming reorganization I will formally receive a leadership title.
I am more on the introvert side of the spectrum. I successfully worked in consulting roles for 10 years and this has never been a real issue. Still when my mentor asked me in what areas I would like to improve, I told him I want to get better at small talk to enable me to more easily and quickly connect to customers and stake holders.
I was able to considerably improve my skills and get in good contact with many people in our office and the customer's office.
However in a recent meeting my mentor insisted that there is no progress what so ever without even asking for input. Which is interesting, as he works on a different floor and we rarely bump into each other. He then went on to ask me about the relation to every single one of my team colleagues. Just to then tell me that I was wrong and my relationship to my team colleagues is terrible. Which again is interesting as my mentor does not work on the team. I am pretty sure he hasn't even talked once to most of my team colleagues.
He then went on to stress in a threatening voice that small talk skills are critical to a leadership role. He insisted that the connection to my team colleagues is so bad that I impossibly can influence them. He hinted at stopping my already announced promotion. (I know from a different source that this is not even in his decision power. This decision has been taken by more senior management. And I got excellent feedback from the senior management.)
