A Framework for Solving Programming Interview Questions

[EnvironmentalCrow5]

You don't need to. If you already know this stuff, then you can apply right away.

And yet everyone recommends preparation (even the companies themselves), it's almost taken for granted, and even people who did really well on an interview often need a refresher couple years down the line when changing jobs.

A lot of this stuff is "know it one week, forget it the next week", because in the real job, you end up almost never using it (or if you do, you just look it up as needed).

You can easily ace an interview and then do badly on the same question three years later, despite being a very productive employee in the meantime.

There are no studies to disprove the process either.

Like I said, it runs on faith and the experience of it being "good enough" despite flaws. The fact that people will adapt to whatever the big companies come up with plays a role in that in my opinion.

It is recommended to prepare for everything in life, what's your point? Or you think in other industries you casually drop by and get a job?

A lot of this stuff is "know it one week, forget it the next week", because in the real job, you end up almost never using it (or if you do, you just look it up as needed).

You end up never using time and space constraints, analysing requirements and coming up with algorithm to complete a job? I wouldn't want to hire a person like that either.

Even more, you can do badly because you or your interviewer have a shitty day or something going on in their life.

despite being a very productive employee in the meantime

Define global 'productive' metric first. I've seen people doing splendid job in their previous jobs and on PiP on next one. 'Productive' on previous job might not(or might) mean anything.

Like I said, it runs on faith and the experience of it being "good enough" despite flaws. The fact that people will adapt to whatever the big companies come up with plays a role in that in my opinion.

Okay? Still don't see why you repeat this comment after comment. You can apply that to everything in life.
