Is it fine to use company laptop for leetcode?

Bruh I have seen people give interviews on their company laptop

Don't risk it, in my previous org, my manager once saw a codeforces tab open while screen sharing on meets, it became a rant "bas ye karlo tum bhi, kaam toh hota nahi hai time par."

As long as they don't have key tracking malware installed.

Meanwhile I'm watching anime episodes

Show dominance by having a couple of tabs open on screenshare

Yesss

Yes

I think its fine to use it.

Yes. Helps increase appraisal at current company (incase they track such inane data)
