Yep, just do it. Worst case scenario is you obtain interviewing experience and can use it to do better at future interviews.
Think about it, this is the WORST thing that could happen.
Best case scenario you could end up with some companies offering you a position
I have had an interview where i did not turn out to be a good fit for that particular company but I still made a good impression and the company recruiter sent my CV to another recruiter in their network which made it time well spent in the end.
Keep in mind that unless you are top dog, cream of the crop with exceptional experience expect to get declined more often than not, so don’t get discouraged if the majority of applications you send don’t invite you for an interview.
