Any tips for finding a job?

I graduated with a Bachelor's of Science in Engineering with a concentration in Mechanical Engineering in May of 2018. I haven't had any engineering experience in nearly 2 years. I had 2 temp jobs that have just allowed me to make ends meet. I tried grad school after undergrad in Materials Science & Engineering but I hated being there and couldn't understand anything to where I just flunked out my first semester. I thought I had everything figured out but I am just extremely indecisive and want to give up on this career path although my significant other with the same degree got an engineering job that summer after we graduated. He tries to push me to keep applying but I feel I'm not looking in the right places and my time since college doing mediocre jobs has become a disadvantage. Plus my interview skills are worse than ever because I may have lost any hope/confidence in myself. How do I find a job in my situation?
