See the fact you work out side will bring a lot to your engineering work, if design related, you know how things should be handled and it will give you and insight to what goes on the mind of the site people when they have to change a battery or something and you have it encased in 4 layers of cables and pipes.
Practical experience is one of the most sought after engineering traits, in railways, offshore etc.
Aeropsace and highly demanding structural design or fluid dynamics its less appropriate but still some is needed.
You just have to keep applying mate and hopefully something will come up.
