The interview process was quite cool and easy to answer all the questions. It was quite informative and a long discussion about projects I handled previously. It consisted of a technical discussion, a manager round, an HR round, and then an offer. It was very cool and easy to answer all the questions.

Behavioral Technical Coding
I had a quick chat with a Talent Acquisition Partner before the main interview, they gave me some info about how it was structured and told me not to stress too much about prep, but knowing a bit about the company would be good. The interview was supposed to be 30 mins on Teams, but it ended up going for 55 mins. I thought it would be two interviewers, but there were actually four! They asked general questions and some technical stuff about debugging in VS Code, operating systems, and working with others. There were also two practical coding challenges: figuring out which coin was heavier from a group of eight using a scale, and checking if two words were anagrams. It was a bit hard to focus because one of the interviewers was in a really noisy place. I followed up afterwards but never heard back, which was a bummer and felt unprofessional.

I applied for FullStack, and went through 3 technical rounds. The first round focused heavily on Java, Spring (Core, MVC, Security), Hibernate, and my projects. The second round involved a programming task for the frontend, and the third round tested my knowledge in Data Structures and Algorithms, covering Array, Linked List, Binary Tree, and Dynamic Programming.
