How to prepare for Technical Interviews ?

Sometimes I just wonder why not send a challenge to the candidate based on the stack that the company uses rather than ask some coding challenges within an hour or so. I think building something real gives so much more insight about the candidate's potential and thought process rather than implementing algorithms that you're probably not going to use in a daily basis, I know it' not true for some cases and this "coding challenges" are meant to see how you solve problems but I truly think (and I see this working where I work) building something real is the way to go when comes to "see what a developer is capable of" and you couldo also bring them over to explain how and why their decisions were made.

After 22 years of experience as a Software Programmer, I had enough, I'm sick, tired, truly disappointed of keep going through this endless nightmare of technical interviews, it has become humiliating. I look aside and I see all my ex-colleagues from High School going to the top of their careers, even those who were truly idiots while I still battling in this endless nightmare. It's not the career I blame, in fact I love coding, but I think the market is a nightmare and I won't recommend anyone to go over this. Seriously, this has destroyed my life, see what the author of that book "Cracking the Codeing Interview" on the 2nd and 3rd paragraph! Sometimes I remember interviews that I would be able to go back in time and have the opportunity to make it different way, I've would never be able to pass it. The outcome is: you can't grow up professionaly this way, you can't dedicate a life to something that add roadblocks any single time in front of you. I read all comments from people quite excited about getting an interview, yeah yeah, I was there before. But you're not going to be young forever my friends, there will be a time when you realize you don't have the same energy in your body and you still have to make a living and pay bills that's when you'll end agreeing with me.

sometimes I talk through the process of solving something off hackerrank/leetcode by myself, its a silly strategy but I think it really helps me talk through ever step. I also go into interviews thinking to just have fun because alot of puzzles they give are tricky (sometimes expecting you to not solve them if the interviewer is really mean!) and helps me loosen up and makes the interviewer at ease to
