So I interviewed for an SDE-1 FullStack position and it had 5 rounds. The first was a 20-minute chat about my projects and some scenario-based questions like 'Why are you looking to switch?' and 'Tell me about a tough project challenge.' It was resume-based. Round 2 was backend-focused, where they asked me to describe a project and then gave me a medium DSA problem using stacks, with no follow-up questions on the project description. Round 3 was frontend, involving JS output questions and building a UI with vanilla JS based on a provided diagram. The 4th round was with the Hiring Manager, where we went deep into my work experience at my current company, with lots of questions about projects, technologies, system scaling, and again, project challenges and reasons for looking for a change. Finally, the 5th round was HR, with about 8-10 typical HR questions, including why I'm seeking a new role.

Behavioral Technical Coding System Design
I applied on LinkedIn and heard back within a week. After a few weeks of profile processing, I had a phone screen. The phone screen's goal was to explain the role, talk about my current work, and see if I'm a good fit. This was followed by an in-person interview the same day. The first in-person interview was relaxed; the interviewer walked me around and we chatted about my work, culture, and past situations. Then came a second in-person interview. There were two logic questions about trees I missed, but the interviewer gave me plenty of time to think. Next was a design discussion, possibly with an architect, where I had to redesign Plivo from scratch. There's also an assignment usually due in 1-2 days, which I skipped because I didn't feel I did well in the interviews.

Behavioral Technical
The hiring process was a joke. I got through one discussion and one interview round. I couldn't finish the second round because the interviewer joined late and the call ended early. They asked me to join the same link again for a scheduled Zoom call, but the meeting wouldn't start on their end. I figured it was a tech issue and told HR, and then they totally ghosted me, not replying to messages or picking up calls for a couple of weeks. I guess I was rejected because I never heard back after multiple follow-ups, even without a proper interview.
