How much you would be able to research would depend on the time that is available at your end.
If it’s a last minute interview and you have only few hours then do the bare minimum necessary i.e, go to the company’s website and make sure you understand what they do and how it aligns to your strengths.
If you have more time available, look up the firm on LinkedIn and see who works there, what the background they came from.
If you’re lucky enough to get a list of interviewers in advance, do all the usual LinkedIn and Google research on all of them and learn as much as you possibly can.
You may figure out the background and area of interest of that individual and you may try to align your responses during the interview keeping the same in mind.
Always keep in mind that any company checks you out in an interview primarily in context of the following six perspective :
- Why you think you are the best candidate for the job
- What are the skills that you bring on board that will grow the company
- What you have that others do not have
- Will you fit to the company culture
- Are you there for the long run
- Will they be able to pay you and whether you will be happy with what they are able to pay
Your response and preparation shall align to place clarity on the same.
All the best !!!
