I'm having that mildly surreal experience with the new job. About 2 and a half months into it, but due to various reasons (brushes with covid, the August / September period for folks doing chunks of annual leave, etc) my on-boarding has been a touch messy and I'm still not really loaded down with any work.
Both my team leader and the technical authority guy have repeatedly turned around to me and made comments along the lines of "we keep hearing good things about your work from people"... and I'm having that blink and "um.. what? I'm pretty much not doing any work just lots of background reading...??" reaction.
