I interviwed for senior software engg position and got a verbal offer.

Round 1: Input list of <file_name, int size of file>, output a dashboard containining total size of the files and top N files (file largest in size)
Round 2: https://leetcode.com/problems/all-oone-data-structure/
The third round involved designing a tag service system.
The fourth round focused on managerial aspects, while the fifth round assessed values.
Overall the interviwered were cooperative and awesome.

The recruiter on the other hand were untrustable.
They promissed a raise over current TC initially (after telling them upfront TC composition before interview and also after 2 interviews)

When I cleared all the interviews the recruiter denied they ever had TC related conversation before and tried to convince me to take a cut in TC and join them.

On glassdoor also I found the same issue recurring with other candidate so just beware folks, keep your hopes low when dealing with Atlassian.
