27M, civil engineer, EU internship + 2 years in Russia, C1 English — resigned because of 65-70 hour per weeks. Is this industry worth it?

I'm 27 years old, civil engineer. Before graduation, I did an Erasmus+ internship in the EU (working for a Turkish contractor), and after graduation, I worked in Russia for nearly two years again for a Turkish contractor. My English is C1 level.

Here's what "normal" looked like in this industry: one Sunday off every 15 days. nearly 65-70 hours a week. Zero public holidays. Unpaid overtime isn't even questioned it's just expected. Saturday is a regular working day, no different from Wednesday or Thursday.

The money was good on paper, but when you break it down to an hourly rate, it's not that impressive.

I eventually hit my limit, resigned, and moved back to my family home in Istanbul. Despite having international experience across three countries, an EU internship, and fluent English. I'm sitting here wondering if this industry is even worth it.

Is this normal in construction globally, or is it a Turkish contractor culture thing? Has anyone here successfully transitioned out of construction into a sector where working 5 days a week isn't considered a luxury? Any advice would be appreciated.
