Advice
One advice I give when applying is to not be afraid or feel like you're not enough to apply. Do it anyway! You never know if you'll get a "YES" from the recruiters. Be yourself when talking to them, try and look at the values of the company you are working for and pinpoint some experiences where you demonstrated those qualities no matter how simple it may be. Also, review data structures and get some coding practice. Know your Java OOP fundamentals, at least the overall concept. Don't be afraid to get rejections. I got rejected so many times before getting this opportunity so keep persevering!
