How to properly train for job interviews?

Question

I am growing beyond frustrating with my job search the past 2 years. A StartUp I worked for ran out of money, so I applied at around 55 companies over the span of 2 months.I got interviewed by around 12 of them. What I found frustrating is:I did 4 coding challenges in one week. Companies who would have paid me less than the job I got rejected my challenges, whereas the company I landed the job, accepted it. So no real signal on to how I "can" perform?Now I got contacted by a few recruiters for interesting companies, and I just wanted to test the waters and went through some coding challenges. 2 companies rejected my technical interview, and I am at a loss. I submitted a coding challenges, didn't think they would invite me to the next step, but they did. I talked about the challenge, what I would change to improve it etc. Was really feeling good afterwards. Now I got a rejection E-Mail saying that they saw some "gaps" in my answers.I literally have no clue. Like, this is my day job. My current company is very happy with me. And yet, another company thinks I am not good enough and sees some "gaps" in my technical ability?I am an engineer, I love critical feedback so I can improve. But the whole interview process around judging once skills seems so arbitrary, that's really hard to tell if I am on a good track or not!Any advice?

It&rsquo;s subjective. The interviewer(s) opinion is what matters. Not your skills or even the questions. Just what their perception of your responses was, and whether they individually like that or not.That&rsquo;s why interviews are so frustrating, there is no &ldquo;one right way&rdquo;.My only tip is try to find the next job while still employed because that circus show can be very stressful if you don&rsquo;t have a job.
