How would you architect a new website?
Generic technical questions with the EM which were fair. The problem is more the technical task – the two people running the interview had zero empathy and no way of making the session a comfortable experience. Asked specific questions about cases with promises and such while in total silence, which led to pressure and very slow response on my side. Gotta admit I was missing some of the bits, and that's on me, but I highly disagree with such an approach – letting people use google is not gonna make people more comfortable – and testing devs on one specific argument is never gonna tell you anything about their seniority.

Round 2 - Architecture - 1 hour - The Frontend team lead took this round. Problem 1 - He started sharing his screen and told me about their platform and the projects they would pick up next. He showed me their UI to write Scala code for a pipeline and asked me to convert that flow to a No/Low code solution. He was continuously using jargon that someone who has already worked with their products knows - such as gems. I had to explicitly ask him to slow down and explain the flow in detail, but he constantly failed to do so. He was talking like I was a member of the team and knew everything about their product. He failed to explain his thoughts clearly and was constantly lacking communication skills. I created wireframes despite lacking context and did my best to give him a solution. He also accepted the solution. Problem 2 - Then he showed me their search component which had an icon that was trailing the text you write in that input. This icon had a jitter and delay as it was moving along with the text. He asked me how I would build and improve this component. I gave him a solution that removed this jitteriness that it had previously. He was skeptical about the solution although my solution was 100% right, I checked that post the interview as well. Problem 3 - Next up, he asked me how I would add a hashtag autocomplete in the same search input. I gave him the solution and he accepted it. He then started talking about a scrolling issue in the same, but he failed to explain what the problem was. We ended the round here. It felt more like a consultancy call instead of an interview where I was solving their product's problems and planning for new features. Result - Moved to the next round.
