Average it was not so much tough they started from coding question to remove the repeating words in paragraph then next golang questions from basics what is go routine ,channel,slice,interface, struct,mutex advantages of go.

WORST INTERVIEW EVER General process - recruiter called and setup technical round - Didn't share any details regarding technical round. Round was scheduled for 30 mins with 2 people (Tech and Non-tech), and went for more than an Hour! Interviewer kept asking theoretical questions from some article he read and expected me to vomit exact same words. He was not at all prepared, just kept firing questions until he come up with more questions, took 40 mins. After this, coding round began. He asked me to print "Hello World!" (Seriously?), and then "prime or not", and then "odd-even", while he kept dropping out multiple times for 5-7 mins. All solved within couple of seconds. 2 Weeks later, I follow up and receive response they are not moving ahead, saying I could not solve the coding problem, and candidate has abstract level of understanding of one topic amongst 100 others he asked during the 40 min firing round. Job description mentioned "Superb communication skills" required whereas the interviewers themselves hardly could speak English and keep up. LOL Worst experience ever, would never suggest anyone!
