I feel hopeless about my interview.

I've been practicing for about 12 hours everyday and I'm still not good enough. I know that with practice I'll get better, but it's a matter of how much practice I'm going to need and if I'll be able to get in enough practice in time

Of course, the recruiter never sent me anything yet about the interview prep. She's supposed to send me stuff eventually. I'm hoping she stalls a bit so that I can do more prepping, since I can sort of figure out what my interview is going to look like (based on what I've googled).

Otherwise, doing ok. Sleeping far too much. Perhaps I am just exhausting myself with all this work...
