Where do you see yourself in 5 years ?

What ?  Who knows what life has in store for any of us, you may not even be alive tomorrow, let alone 5 years from now.

I am so so glad I am out of the job market, it really was a sickening experience, I was never who they wanted.   Not enough experience, or too much experience, or too much schooling, or my clothes were not corporate enough, etc.

I am done !

"How many fingers am I holding up?"

The first time they asked "why do/did you want to be a ..." (insert whatever you're applying for) caught me off guard, though I should've seen it coming of course.

I think it's not a useful quesiton to ask. People just make stuff up anyway, even if they believe it themselves. It's usually an answer that matches 50 jobs, 47 of which they would hate. You want to be a theoretical chemist because you're curious, like challenges and want to help the world by making it better understood? Why not do deep-sea diving instead?

The correct answer, in my view, is "because I've been doing it for a while and I really like it". But it isn't the answer that'll get you the job. At best they'll ask "what do you like about it?", which is even more useless.

So probably you should just give them the answer they want to hear. It's not like it'll make a practical difference for anyone, anyway.
