How to find a better job after starting a new job?

So i was laid off this week but a job called me for an interview already. Its job within 20 minutes from me. Similar to what I used to do but different industry. Problem it pays way less.

Within unemployment and savings I hqve enough to last 6 to 8 months. The advantage of taking this job if offered is its more than what unemployment pays but it isnt enough of a salary to cover most of my bills so if I took this job it would only be temporary.

The problem is if I start getting interview requests if hired dor this new place how would it be possible? I cant keep taking time off to attend interviews if get laid off quickly.

But while I have savings any extra money will help prolong it.
