I’ve never actually had a colleague quit while I was there, buuuut, I did have a colleague disappear, here is that story:

I get hired by this colleague, seems like a nice, perfectly reasonable guy.

I’m supposed to be mentored in the codebase by him after I start.

Literally the day or day after I start, he gets a tap on the shoulder from someone in HR while he’s on the phone. He says he can’t come because he’s on the phone.

The HR woman insists, tells him to leave *everything* and he never returns.

Turns out the police were downstairs to arrest him.

He got caught up in Operation Yewtree which for those that don’t know, was the UK’s sting op on historic pedophilia cases.

MFW my manager gets arrested and the senior dev is too busy to mentor me, so I basically have to sink or swim 🤣

I am being mentored all of my life.

Parents mentored me that I won’t get to that school and I should pick other one ( I got there where I wanted ).

Politicians mentor me to make me happier by taking more and more of money I earned ( I am not ).

Advertisers mentor me to buy their products cause those are best products in the world ( I buy cheaper versions produced in same factories by same people ).

My boss ( when I got one ) mentored me that everything is simple and could be done in 5 minutes. ( after reading some dummy article )

Coworkers are mentoring me everyday that it’s not their fault ( It definitely is ).

Telemarketers, emails, sms messages are mentoring me about my future, don’t miss that occasion, it’s best for your life ( No it’s not )

Celebrities are mentoring me how to live my life to become a successful person ( Yeah right, cause they known how to become one right after they were born ).

Now I see I am starting living in times where computer will start mentoring me how to live my life. ( Sometimes it already is )

What’s left is doctors start mentoring me about my illnesses and children ( if I ever have one ) mentoring me about how dumb I am.

Then I can finally peacefully die and don’t come back to this mentoring hell.

If ever you felt imposter syndrome, it's after your senior experienced colleague rewrites an API you built... You've been chipping away at it for months, making it faster but reaching the limits of the functional but flawed original design.

In one week he starts it as a side project, and fixes the whole thing, soap to nuts... I need to sit down with that guy more.
