But in the context of job interviews.. It applies. But also that applies in trading, if you have a bunch of experience winning or losing, that's useful experience and I want your input on my team. The fact that you cherry picked is built into the evaluation. You have experience. Whether or not you have some innate talent for it is aside. I care about your experience.
Yes in interviews it is expected and people do cherrypick. But the ability to cherrypick can show a lower skilled person in better light compared to a higher skilled person who may not cherrypick as well or tends to not like cherrypicking the best examples since it doesn't feel honest. Sometimes this honesty can work well, sometimes not. Sometimes if honesty doesn't work well it just means the job wouldn't have been a good fit anyway, but other times it is just putting you at a huge disadvantage.
I have a friend who is somehow super good at that, it is fascinating to me. But he can't be bothered to do actual work. He performs extemely well in interviews, gets high paying job, and then stays there for 3 months, gets bored. Of course he doesn't put that on his resume. He doesn't really lie, but he definitely cherrypicks, embellishes etc. I am kind of the opposite of him. I have stayed at the same place for years and am naturally passionate about software eng, but troubled socially. He is very confident and has no shame.
