Atlassian Frontend Engineer interview questions

Spoke with a recruiter, had a tech screen, followed by an onsite. The onsite was not a great experience. It felt more of like a Frontend Developer than a Frontend Engineer. There was 4 interviews in the onsite and each one felt awkward as the last. The manager at one point said to me that he accused me of reading off of a script or notes. It made me feel a bit disingenuous and uncomfortable. There was no algorithm or leetcode questions asked. It was a straight up ES5 JS questions. During the implementation, I mentioned that I wanted to use a while loop, but he said that's incorrect and you have to use recursion for the problem. At the end, the interviewer muttered that I'm completely wrong in my implementation and when I mentioned that I heard that, he said that he didn't say anything. The entire process made me feel terrible and I would not recommend an onsite process. The recruiter and tech screen were great people, but I did not get a friendly sense from the team.
