When getting feedback about my CV from coworkers, my impression is that very few of the people who personally interviewed me ever read my CV before hiring me — recruiting websites like LinkedIn, Xing, talent.io, honeypot.io genuinely seem to have replaced the CV in many cases.
(If you're wondering how I managed to get that kind of feedback from those specific people, it's all the times places have run out of money or the investors wanted a completely different direction with no iPhone app).
As an introvert this has been a painful lesson to learn, but the reality for me is that I’ve only landed jobs at 2 out of the 7 companies I’ve worked for in my tech career where I didn’t know someone that would vouch for me from the inside.
