I agree. Amongst the engineering disciplines, the job market for civil is really hot. You have a government internship as a freshman!!! You’re doing all the right things.
Keep at it, especially with internships/co-ops, and revisit the idea of grad school later. I will be surprised if you “need” a masters, so your decision will likely be based on you wanting the degree for other reasons. Experts in your field will know best, so keep seeking out and taking their advice as you go.
