A lot of young installers apply without meaning or purpose and are just looking for a job. Many of them just want to sample and dont make it. Lots of callouts after long work days, inclement weather and heatwaves but those who show up are well compensated. Dont play video games until 3am. Do eat healthy, hydrate, remain positive and learn the job. Be reliable and professional and don't feel entitled if promotions dont come after a few weeks of hard work.
