Not an overly helpful article with any new insight or info.
I also get why you say 'rehearse interviews' but is this the right approach? To me, rehearsing answers strips the authenticity out of how I respond and turns me into a robot, in a way. I'm sure this works and benefits those who can do this (giving them jobs they may not even be the best for), but some of us literally can't fake sincerity and when we do, it shows.
I'm a nice person, have tons of past design experience (am new to UX), work extremely diligently and hard, have a good portfolio, get a decent amount of interviews (not a lot, but some) — but it rarely goes past this. I just can't bring myself to be fake in an interview, it does a number on my mental.
Not to mention, a lot of people don't have a ton of friends or colleagues in the industry to lean on and aren't great at socializing in general (even online)... I physically don't always know how to do it. What do you suggest in this case? It's like a big networking game and I don't know the rules.
