What skills are really important to have when working as a software engineer?
What are some computer science or programming skills that you didn't think you'd need much of that you ended up using a lot as a software engineer?
Logic and Reasoning.
Be someone who likes to learn...because with programming you will always be learning lot of new things. Dont ever make that appear scary to you.
Also depending on what area you get into for Programming (like programming for Business functions, or gaming or cloud application or mobile application development etc etc) you will need to get into other stuff like algorithms (shortest path, tree search etc etc).
Finally, Patience. Have a lot of it, as it helps you grow in being a good Programmer.
Ultimately, you're writing code in support of end users who work in a concern whether for profit or non-profit (e.g. business vertical such as banking, retail, energy). There is a big divide in knowledge between a programmer and a financial analyst or a team running an oil rig. Therefore, to the extent possible you need to broaden your vision of programming to a vision of domain specialization or at least an affinity.
There is a great book by Eric Weiss Domain Driven Design which exhausts this strategy. It's not an easy read and probably not ideal for someone just getting started in programming, but it's a very important consideration in the context of your overall career.
The good news is, assuming you have other interests beyond programming, you can 'minor' in some other field that sparks your interest and take that minorseriously as something you may want to develop so you can bring that domain knowledge to your programming knowledge.
Hagen recommends the following next steps:
Being able to support your team members, because when you work well together the entire team's productivity can go up.
Problem solving - it's about the how and not the what, and making sure you're solving the right problem.
