Motivation for Interview prep

Hi guys, I'm thinking of starting interview prep but not able to get motivation for doing so. My current company has slowly started becoming toxic and the pay disparity among the employees of same level is huge. Although the pay thing was not a major issue few months back, the toxicity has started affecting me. Now coming back to the point, being in bangalore, doing daily WFO, I'm not able to find time during weekdays and on weekends either I'm exhausted or occupied with some household work. Can you guys please drop in your tips on how guys pull off preparing while working? PS: I'm currently working as an SDE 2 and looking for senior SDE 2 roles.
