The ugly truth
Having self-doubts about your accomplishments and your abilities, and having the fear of ever being exposed as a "fraud"....
For further actions, you may consider blocking this person and/or reporting abuse
When mentoring it's important that you don't try to be the fake person who knows everything; never be afraid to say "sorry, I don't know the answer"
It's much better to open a web browser, search for the information you require (together), learn something new and discuss with the mentored so you both gain new knowledge.
I'm astonished by the number of times I've come across "senior" devs giving fake answers or bluffing their way through a stream of tech garbage ending up with everyone more confused than when they started!
Totally agree... that's what I was talking about when I wrote about getting your facts straight.
That's some really good advice John, thank you for sharing!
