Google | Test Engineer | Warsaw | Oct 2021 [Pending]
Summary
I had 5 onsite interviews over 3 days for a Test Engineer position at Google in Warsaw. The rounds covered string manipulations, a variation of Number of Islands, basic testing, and 'Googliness'. I feel my interviews went well and am expecting a positive outcome.
Full Experience
After the preliminary rounds, all my 5 onsite interviews were scheduled over the course of 3 days (2 + 2 + 1). Round 1 focused on string manipulations, which was an easy problem if you are comfortable with two-pointer or sliding window approaches. Round 2 presented a slightly variated version of the classic Number of Islands problem. Round 3 involved more string manipulation with two follow-up questions, which started to get tougher. Round 4 was centered on test basics, and finally, Round 5 assessed 'Googliness'. Overall, all my rounds went pretty decently, and I'm currently expecting a positive outcome.
Interview Questions (1)
I was presented with a problem that was a slightly variated version of the classic 'Number of Islands' problem. While the exact variation was not detailed, it would typically involve grid traversal using BFS or DFS.
