I had the worst interview of my life today. I guess you could consider it a big N company. Definitely not an entry level position but not senior level so I can treated like entry level and get asked algo questions even though it's been years since I used a bubblesort algorithm (etc). DM if you want more information. I will premise this an overall question that doesn't require the reading below: does HR personality check the coding interviewers before they make them interview candidates? Have you ever had an interviewer interrupt you throughout the process without even hearing your full solution even if the solution is valid? Summary: I leave work early take PTO for a phone interview on HackerRank. Heavy accent and softly talking but a little bit snippy when telling me it's heard to hear me. That's fine though. I know bad signal is annoying so I put a headset on and it's clear. Explains interview format. Standard stuff. First part is about career. Second part is coding challenge. Asks me about current project, I explain {dev job 2}. Not bad. He responds "nothing about this {dev job 1}" I forgot how he phrased but i remember it be really passive aggressive. Like implied that job 1 was a joke. Explain job 1. He then asks about concurrency question related to work and I responded how I deal with concurrency issues now. I thought I would premise it with explain what the problem comes out of and then detail how I solved it. But while explaining it he cuts me off (quite loudly and aggressively), "TELL ME HOW YOU FIXED A CONCURRENCY PROBLEM." I almost wanted to reply saying if you relax and wait I will tell you. But I'm professional I laugh it off and tell him and shortly explained what it solved. Fine lets move to coding question Gives me a coding question. It's pretty simple but he makes it unnecessarily difficult the more it goes on. He tells me lets talk about the solution. Which is fine. I do the only issue is that he proceeds to shoot down everything I say. And not even like massage the idea like "oh okay how would you do that." Like full out like "that's dumb". As if I saw this problem for an hour and had an idea of the solution already. Like I'm really not proposing my solution I'm talking out loud because in the coding interview book they suggest to talk about what you thinking so they can see your process. It's really had to get an idea and concentrate when you are just talking and then someone interrupts you and tells you that's dumb. Then I was like fine, I'll go with the second part of the suggestions from the book stating, "get a brute force solution then optimize it." Well this guy basically began to mock me for suggesting such an iterative approach. Like I know there are memory issues when the number is huge like I'm trying to get a solution for you. After the interview I looked up possible solutions and all solutions had replicating the data structure or using a bubblesort. Cool but he said I couldn't modify the original data structure and I couldn't create a temporary data structure to sort it because what if there a billion n elements. So that implies an iterative approach. So at this point I'm just like what they hell. I start spinning my wheels. This guy has made me feel stupid at every suggestion. So then I went back to the iterative approach just to get a solution and then I suggested a queue or stack as a secondary data structure and that I'm trying to think what would be a better structure for what I'm trying to do. Then he asks "do you even know what a stack is?" This is the point where i want to hang up. But I'm like whatever, I worked with abrasive people before. Officially stuck because I haven't had a second to think without this interviewer interrupting me every two seconds talking down to me, I began to lay out the requirements he has now laid out in front of me that complicated the original issue. And explain how possible solutions are shot down by this new condition you stated. He responds something on the lines of "I don't know how to solve it however you want to solve" lol not really. Then he says well this only suppose to be an hour interview and its been 30 mins. I swore I heard him say you aren't smart enough and I said "excuse me?" He slowed his horses and said the onsite interview questions are harder so I think we can just stop right now. I took me every piece of my soul to say "Oh okay," instead of point out how terrible of an interviewer he was. I never had an interview be so disruptive and disrespectful. I swore it's like I took up to much of his precious time when I had to use my vacation time to take this interview so nicely placed in the middle of the work day. Now I'm questioning how is this guy the guy interviewing people. Was this guy just going through the flow before outsourcing this position?
