Datadog SWE interview

I've got the first round (video tech interview) of the Datadog process coming up in just over a weeks time, from glassdoor and blind it looks I'll be asked 2 LC style questions. Are there any specific areas I should brush up on as I'm quite rusty with LC but willing to prep for the next week. Has anyone been through the process recently and have any more insight?
