Soft skills were what put me ahead of my "competition" in both of my software development jobs (hired for the first in May 2018, then moved states and hired for the second in September 2018).
I practiced algorithms, got decent at whiteboarding, and learned to speak my thought processes aloud as much as possible even in times of uncertainty. But above all, both hiring managers told me, the soft skills I've developed shone through and outweighed any technical skills they thought I was missing. My first manager even told me "you can teach technical skills, but teaching someone to communicate and work with a team is much more difficult."
So, long-ish story short: In my experience know your job-related stuff, but don't skimp on honing your communication and soft skills!
