There are ~6 ways of structuring a fictional story. Out of those, 1 seems interesting while interviewing at tech companies: man in the hole.
Or:
Goes like this:
“This story occurred when I was a tech lead of X people”. So, this is the base line. Or anchor.
Shit happened one after the other. ~3 times is ideal.
“I did X, Y and Z” to find success.
“At the end, I, the team or the product came out better than before because of …”. (Notice that the final line is better than the starting point.)
Important:
Magnitude of both sides of the U and, consequently, its depth matter.
First half of the U == how big the challenge; 2nd half == how big your actions and whether they are appropriate with your targeted level.
