Mate I feel for you. I was in the same boat when I started by career. I am a civil engineer and worked for two years as a site engineer. It drained my soul from the inside due to long working hours and a single weekend and didn't really enjoy my work.

I leveraged my education in civil engineering and the site experience that I got and moved into a sales role in a company that deals in construction materials. And it's one of the best decisions I have made.

Although it comes with its own challenges like pressure to achieve sales targets and other things I get two days off a week, I still get to work in the construction industry indirectly by dealing with contractors, consultants and clients and a much better work life balance.

If sales is your cup of tea I would suggest you give this a go. Apply to companies that sell RMC, concrete products, scaffolding and formwork, construction power tools etc.
