First part is pretty simple, a culture fit/HR interview. Second part is technical interview, asking about projects you worked on and that you're proud of. Defining some concepts about web development

I applied through their website for back end engineer position and I was contacted by their HR rep from New York a week after. She scheduled me for a video call. We had an amazing conversation, she is extremely nice. She explained the whole process and scheduled me for an in person interview with two technical leads. I had an amazing interview with them. The feeling was mutual so they scheduled me for a third in person interview with VPs of engineering. One guy sat beside me and one guy in front. 5 minutes into the interview, when I started talking about myself, the guy who sat beside me opened his tablet and went on his social media or maybe slack and stared scrolling down. I was in shock and very distracted. It all went down hill from there. The guy in front of me, who was asking most of the questions, was extremely condescending, he often made fun of my responses.
