Technical Coding Behavioral
The process was supposed to be good, but it was a mess. 5 rounds for an entry-level role, which took a whole month, plus 2 HR rounds, 2 technical rounds, and 1 managerial round. The entire thing dragged on for 4 months, felt like I was ghosted. They used whiteboard coding and practical exercises like LeetCode problems. The interviews themselves were okay, and the interviewers were professional. They wanted a background check before any offer, which is a red flag. I got the 'greenlight,' only to get a generic rejection email on Friday afternoon, 10 minutes before closing time, leaving me with a terrible weekend after 5 rounds and 4 months.

Behavioral Technical Coding Other
I was contacted by the recruiter on LinkedIn. The process had 3 interviews. The first was with the recruiter, about 30 minutes. They explained the role and company, and we had a brief English chat to test my level, which is required. The second interview was technical, fully in English, and lasted about 1.5 hours. The first part focused on Java with some live coding problems. It was quite relaxed, with time for questions and even research. There were also questions about Java, React, and Angular. The second part was with a project manager who asked about my background and experiences, plus more on JVM, Big O, and code analysis. The manager was really nice, and we had a good chat. I felt the questions were tailored to my profile, not standard ones. The third interview was with HR. She didn't speak Portuguese, so it was entirely in English with basic HR questions, which was straightforward.

Technical Coding Behavioral
It was a 3 round process. The first was a Technical Interview, starting from basics and covering frameworks like Angular/React. It was quite elaborative, involving writing 5 programs (3 in javascript, 2 in Angular) and answering about 10-15 questions on the Frontend stack. The second round was a Managerial round, with questions about Agile, task division, time management, pipelines, and so on. The third round was the HR round, which, unlike other companies, was a full-fledged interview with behavioral questions. So, only 3 rounds but you really need to perform well in each.
