Hackerrank test, coding round with the Director, onsite.

I have given many interviews with different companies so far, but this is the only company where employees have too much attitude and insult interview candidates.

I work for a startup that provides security solutions for the Cloud. The interviewer, a senior engineer who had worked at Visa for almost a decade, had no idea what my company does. He sarcastically stated that nowadays, startups using the words "Cloud" and "AI" are more like buzzwords, and he never let me explain.

I felt very bad. I would never reapply for any job at this company.
