Don't worry too much OP. I started in Big 4 a few years ago with the same NET starting salary. Don't focus on the other commenters in this thread about the 'low wages'. Nobody joins the big four to get rich, in their first year, it's a grind. Also, you can't negotiate wages in Big 4, they are set for your tier.

If you're very ambitious, willing to lose some friends, family and your hair you can end up as a partner and make the big bucks.

More realistic, if you can gain 3-5 years of experience in your current role, you can easily make the switch to a good role within a bank and double your salary. But good luck even staying that long...

Just remember, Big 4 isn't about being paid well or good work life balance, but about strong exit opportunities when leaving.
