About this book
You've seen the headlines: data science is the sexiest job of the 21st century, six-figure salaries, endless demand. But what does it actually feel like to sit in that chair on a random Wednesday? What are the boring parts? What do you do when your model doesn't work and the deadline is Friday? And after the hype, is the pay actually worth the years of math and coding you'll need to invest?
This guide answers those questions with concrete details, not inspiration. You'll get a realistic hour-by-hour look at the work, a self-assessment checklist to honestly evaluate your fit, a comparison of education paths with real timelines and costs, salary tables with entry-level to senior pay across industries, and a practical job-search playbook — including what interviewers actually ask and how to build a portfolio when you have zero experience. It's written like a career counselor who's seen the good, the bad, and the tedious parts of the job.
No vague promises about 'unlocking your potential' here. Just the facts, the numbers, and the honest trade-offs, so you can decide if this is the right path for you — and if it is, how to actually get there.

★★★★★I'm a career-changer in my late 20s, and this was the most grounding thing I've read on data science. The salary ranges and the self-assessment in Chapter 2 were realistic, and Chapter 1 gave me a real picture of the job — including the parts that aren't glamorous, like cleaning data for hours, which I honestly needed to hear. The chapter on breaking in with no experience had some useful, concrete steps, but I would've liked more on how to actually get that first interview when you don't have a CS degree. The section on what interviewers ask was solid, though. It's a good reference to have before you commit to a bootcamp or a degree.
