Informal interview which would have been followed by 3 short interviews then finally a culture fit interview. I don't know much besides this as I didn't get past the first stage.

It seemed like it was the interviewer's first or second interview.

There were a few questions about my experiences and then a very very basic coderpad which I solved after providing a couple of potential solutions.

The interviewer asked me the complexity of the algorithm and he didn't really seem to understand complexity analysis which made the whole thing a bit awkward.
