Machine as in ect or rtms? Did he ask you to appy for a job while you were getting treatments? Odd.

It sounds like you may be unsure about appropriate casual relationships with new coworkers given that you are a patient too?

He sounds lonely or needing someone to dump on. If you want to befriend someone like that, why not, if he's your coworker. Maybe he's a bit quirky. Too much too soon like that, and knowing many psychiatrists have a good deal of issues, i might stay away, and just be polite.

If you feel rejected by him, I'd imagine that happens at other times too.
