Yeah. This is absolutely true. Honestly, I think my grades and experience are good enough but aren’t as strong as many people I know. But I’m good with words and good at interviewing. So I think my essays and my interviews are what got me in.
Grad school apps are a total crapshoot. It’s a hit or miss. There’s so many factors that are so hard to control.
My advice would be to brush up on interviewing skills. Clearly something stands out with 6 interview offers. Somethings getting lost once you get there. It takes a lot of practice and interviews are stressful af so it’s understandable. But you’ll get there.
