A friend of a friend has on multiple occasions aggressively asked how my self-study for software engineering interviews is going. Most recently I answered very briefly, because I find it too nosy and the person to be arrogant and presumptuous. I don't like for example that he's convinced that I seem too calm about the job interview preparation process and that I don't push myself hard enough.
Initially I just listened to him rant over the phone, and after he realized he was doing all the talking he then asked for my input and I answered honestly. Then he would "check in" with me over Messenger or when I ran into him at a party it would be the first topic of conversation. Since he didn't change, one thing I did when he was doing the same to someone else right in front of me was I asked "What do you mean?" and he simply acknowledged he was rambling. I've been distancing myself from him as of late which is tricky since he's in a few of my friend groups - I have no desire to "win."
How do I convey that I'm not interested in him essentially interrogating me and opining in career-related matters?
