I applied online. The process took 4 weeks. I interviewed at Chain.io (Korea, VA) in Oct 2022
Interview
Had 4 interviews in total, all of which I thought went quite well. This left me feeling super confident that I might have gotten the job. Got completely ghosted after that, never even heard a peep.. Good times.

Question 1
What is destructuring? What is your favorite npm package?
I applied through a recruiter. The process took 2 weeks. I interviewed at Chain.io (Philadelphia, PA) in Aug 2022
Interview
First interview with VP of engineering, 2nd round is with HR person describing the culture and then the 3rd round was technical with 3 engineers.
For first 2 rounds I got a good vibe from the people and they were quite nice.
For technical round, 2 of the 3 engineers seemed nice and if they didn't want me on the team they didn't show it. But the 3rd engineer was a rude, condescending grown child. Made it very clear with his tone, even before any tech questioning started that I don't belong on his team and I wouldn't be getting any offer. He would often roll his eyes at me, talk down at me with a condescending tone, openly showed impatience throughout the interview. When I got the news I wouldn't be moving forward in the hiring process I wasn't too surprised but I was very relieved.
