It was ok and pretty formal to crack. I got link through Skype and interview was also done through an intern. They also do interview for training purposes. I had an neutral experience with Gao Tek interview.

Held remotely over skype, Was asked to give an introduction about myself. The interviewer then asked me relevant questions. I was asked if I had any questions I wanted to ask. The interviewer concluded after submitting a perosnality test.

the interview was quick. I was asked a few personal questions likely as pleasantries, then was asked to answer a written test, which asked general questions not relating to the job, which is mostly graded on spelling and grammar. after finishing the interview and receiving an offer, it took a month or more for them to get back to me and schedule my first day. when I showed up on my first day there was no one there to explain the job to me or my duties.
