Atlassian | Senior Backend Engineer Interview | Bengaluru
February 2, 2026 · 30 reads
Summary
I had an interview for a Senior Backend Engineer role at Atlassian in Bengaluru. I was presented with a challenging Data Structures problem, 'All O'one Data Structure', which I found difficult to solve within the time limit, resulting in a rejection.
Full Experience
Round 1 - Data Structures Round
One word - Cooked :(
I came up with the approach. I coded it as well but this has a lot of edge cases that I needed to consider.
I tried to solve it after the interview and it took me 2 hrs. There's no way I will solve it in the interview in 45 mins if I haven't solved it before. So, practice well bro.
Verdict
I got a rejection email on the same day.
