I have some questions need your help thanks
I plan to become transportation engineer and just graduate from college about 4 months ago so:
1) Is traffic engineer in real life consider less stressful compare to geotechnical or structural ?
2) Will traffic engineer overall excited, funny and more interesting of environment work, cleaner workplace compare to structural or geotechnical ?
3) If I have 0 internship in college, so is it better to take a whole year off do 3 internships (spring, summer, fall) and start entry level after one year so will it affect my employment ?
4) Will I need to put 1 year experience of working doordash on my resume or if I should leave it off ?
Thanks
