Align Technology Software Engineer interview questions

Very technical. They had 3 rounds of interviews with last round being a onsite interview with 5 members. 3. given a set of points in 2D and I need to calculate the diameter which is the maximum distance between any two points in that 2D space. 3.1Use multithreading to make it faster. Use templates to make it generic.

Applied online. Reached out to by a recruiter. Recruiter was nice and set me up with an initial technical interview. 1st part of technical interview was an easy coding question (palindromes) to work through. I did so no problem, but when I asked the interviewer about what constraints I had to take into account he implied that there were some, but wanted me to guess them. I did guess but he wouldn't confirm if my assumptions were safe or not, so I just implemented what made the most sense to me. He didn't seem satisfied with this but wouldn't say way or give me any more requirements. 2nd part of the technical interview was a systems design exercise to design the backend for a hotel website. This wasn't a backend position, but whatever. Similar story to the coding question: interviewer asked vague questions with multiple answers, wouldn't work with me to clarify any assumptions, and seemed to want me to read his mind. When I asked him about company culture, he basically said it was a really stressful place to work. I received an automated rejection a couple days later. Wouldn't recommend.
