Go for it! I was hesitant to apply for this internship thinking “oh there are plenty of other people more qualified than me who are applying” yet, I trusted myself and tried my hardest during the interviews. Technical knowledge can only get you so far. Instead, the most valuable skill is being able to adapt and think on your feet. You will feel out of place but it’s normal! You are an intern, you are there to learn and expand your skills, just take a deep breath and try your hardest!
