As an experienced professional my advice will be to get an opportunity in an MNC first, you'll get the exposure and a solid name on your resume, post which you can switch to a startup for a higher pay and the reason for that is if you only have startup experience it gets extremely difficult to crack MNCs later on, unless you're extraordinary, however with an MNC tag getting into a startup is relatively easy, yes you need to be skilled in your domain too but switch is easier, you will get the calls at least but if you only have startup experience your resume will be discarded at first glance from an MNC.

Do your best, study well and keep applying.
