I'll try to add at least one thing for each round of interview from what I remember: HR Intro call: Basic questions about your background and why you applied for the position and the company. Tech Interview: It was a live coding session (sadly don't remember the name of the coding environment) of three short problems using JavaScript. Testing was an optional part, but I tried doing it anyway. General Tech Interview: This one was questions regarding how I reacted in certain situations, like, for example, how I dealt with someone with I had differences with or to talk about an issue I had faced. It's an interview to see how you fit in the team. I recommend STAR for answering these questions. Sadly, I don't remember more questions. System Design Interview: This one was a bit more challenging to me. Questions were regarding, for example, what happens behind the scenes when you access a website, how you would choose the tech stack of a project. Sadly, I also don't remember many details. I recommend reading at least the first chapter of the book “System Design Interview - An Insider's Guide" by Alex Xu.
