In Tech, I really prefer 1 -2 pages tops in a short crisp CV; no extra text and weird sales pitch.
Why? 1) Your actual experience, what you did, how your career progressed etc. matters most. That stuff goes beyond promises, wishes and dreams - but shows the sweat and tears. Github repo links etc: big plus 2) We are all humans that have a mortgage to pay, feed a family etc. I’m not disappointed or mad if people apply for a job for the money and fame. 3) I probably have yet to meet an engineer that would enjoy writing prose about why a job posting and company “were his life long dream”.
I never ask why people apply for a job or switch either. Personally, I would never have had a good answer my self - because you seldom know what the actual job or culture or projects will be like.
