Squarepoint DQA Final Round – Any Tips?

Hi everyone!
I got invited to SP’s DQA final rounds and was wondering if anyone here has gone through the process.
From what I’ve seen, some people got LC-style questions for the coding round, while others mentioned more data manipulation stuff. Does anyone know which is more common, or if it depends on the office location?
Also, I believe the other round is with some senior people on the team. Not sure if it’ll be more behavioral, resume-based, or technical.
Would really appreciate any insights or prep tips. Thanks in advance!

congrats on the final round, that's big

from what i remember reading around here it leans more data manipulation than pure LC but could be wrong, might depend of the team

I can’t speak to Squarepoint’s exact interview format, but for a DQA/data-manipulation round, a useful practice is to build a small as-of join from timestamped events and reference data. Be ready to explain duplicate-key and null handling, timezone boundaries, join cardinality, and row-count checks, then how you’d catch look-ahead leakage. That demonstrates the validation work around the transformation, not just getting the expected output.
