This review is from personal experience so that it may vary for others. My supervisor was passive-aggressive and mentally abusive. I was hired to be remote and learnServiceNow from scratch. The resources they give you are limiting, and you are expected to be an expert after a few months.
My boss would call and message late at night about work. He would play mind games like tell me to ask questions and then when I did ask me why I didn't know that.
I lived in fear of him the entire time I worked there. I ended up in therapy because no one trained me, and I worked 12-14 hours a day to try and make up for it.
Unless you're desperate, avoid Highmetric. They'll say they're flexible, and they yelled at me any time I was away from my computer. The company is a toxic place to work.
