Ask HN: Is it possible for someone to not be cut out for software engineering?

I'm pretty new to software engineering (~1 year out of college as a CS major) and am having some serious problems improving my skillset (particularly with interviews). Background: - I worked as a linux sysadmin at a startup before going to school for CS. After 3 years, I graduated with a decent GPA (>3.6) and a couple internships at a large tech company. - In college, I always felt like I had to work a harder than most of my classmates in order to get the same result.

However, I've been prepping to jump to a different role for a few months now. - Recently (past 1.5 months), I've spent 1 - 3 hours per day on tech interview prep using CLRS, Cracking the Coding Interview, etc. My current target is a role at one of the "big four" tech companies or a high-quality startup doing either webdev or inf
