3 months notice period need suggestions to upskill

Hi everyone,

I am currently in notice period and already grabbed an opportunity with a telecom giant (fully remote) at 20lpa fixed. As I have 3 months of notice period I am thinking to upskill and move to other domain mainly in a tech background. I am thinking to switch to devops role and know the basics too but don’t have experience in devops tool. From the devops experts or any software engineers, can someone please confirm If I give closed to 3-4 hours daily will I be able to grab new opportunity in devops matching the current offer?

Thanks in advace!
