Editorial context: this is my retrospective on a data career from graduate school through leaving Apple in early 2021. The compensation figures are personal historical estimates from the original account, not verified payroll records or current salary benchmarks. The original “14X salary” headline compared base pay with a later equity-influenced income estimate, which are not directly comparable measures.
Six corporate jobs, changing priorities, and a move to my own projects
I worked six corporate jobs before leaving Apple in early 2021 to focus on skills.ai and SQLPad, two projects I started during Covid. They were demanding more of my attention, and I chose to work on them full time. This story is about the choices and circumstances that led there, not a formula that guarantees the same financial outcome for someone else.
Graduate school and an unexpected change
In 2004, I came to the United States to study advanced mathematics after completing my bachelor’s degree in China. William & Mary’s Applied Science department offered me a full scholarship and a part-time research assistant position with a $1,500 monthly stipend. I remain grateful for that opportunity.
In 2006, my Ph.D. advisor moved to another university to start a new program that did not yet have a place for me as a Ph.D. student. I had to decide whether to find another advisor or leave with a master’s degree and look for a job. I was interested in working with larger datasets than the costly experimental samples available in my research, and I chose the job search.
My first industry job changed everyday life
I accepted a data mining research role in Boston with a reported $70,000 annual salary and began my first full-time industry job in 2007. The increase from my graduate stipend felt enormous. I replaced an old Ford Escort with a new Saab 9-3 and then discovered how different a gross salary felt after payroll deductions and a car loan.
That first industry salary gave me options I had not previously had: a computer, a television, and small purchases that made everyday life easier. In the original story, I remembered that period as one of the happiest, even though later compensation figures were much larger.
Moving west and joining Amazon
Between 2008 and 2010, I changed jobs and moved to Seattle, including a role at Specific Media. The original salary sequence was $70,000, $93,000, and $100,000. The percentage increases printed beside those figures were incorrect: $70,000 to $93,000 is about 32.9%, and $93,000 to $100,000 is about 7.5%.
In 2011, I joined Amazon with a reported $110,000 base salary, a $70,000 equity grant vesting over four years, and sign-on payments of $35,000 in the first year and $40,000 in the second. Those components are different: base salary recurs, sign-on payments follow their own terms, and an equity grant is not all received at once. The original rough annual estimate should not be treated as a reconstructed compensation statement.
Chegg and the uncertainty of equity
In 2013, I joined Chegg before its IPO with a reported $190,000 base salary and stock options whose potential value the hiring team described enthusiastically. I moved to Silicon Valley and met people who became an important part of my professional network.
The original article generalized from that experience to the performance of the entire 2013 IPO market. That broad claim was not supported by the account and has been removed. What I can preserve is the personal memory: I still remember the company party when Chegg listed on the New York Stock Exchange. A memorable event and a recruiter’s valuation estimate are not evidence of a predictable investment outcome.
Apple, a startup, and returning
I joined Apple in 2014 after a recruiter contacted me on LinkedIn. I had long enjoyed Apple products and spent considerable time preparing. The process took more than two months around the holiday season. I accepted a small base-salary reduction, with equity and sign-on compensation also part of the offer.
I left to found a machine learning startup in 2016 and returned to Apple in 2017. In the original retrospective, I reported receiving roughly 5,000 Apple shares in 2020 and estimated total corporate-job income at about $1–$1.1 million using a share price quoted at the time I wrote the article. Repricing shares at a later date is not the same as documenting their value at vesting, realized sale proceeds, or taxable income. The original account does not provide the records needed to reconcile those measures, so the estimate remains a clearly labeled recollection.
What I take from the experience
Equity appreciation played a large part in my reported outcome. That makes timing and market conditions part of the story, alongside work and career decisions. It does not establish that joining a large technology company and staying through a vesting period reliably produces a seven-figure income. The original share-price comparisons and universal vesting examples have been removed because they were date-sensitive and not a substitute for an actual grant agreement.
When comparing roles, separate the work you will own, the people you will learn from, the recurring pay, one-time payments, and the documented equity terms. Unknown future stock values should remain unknown. The large-tech role checklist explores the non-compensation questions as well.
My most useful memories are not only the largest number in an offer. They include a scholarship, the freedom of my first industry paycheck, mentors and colleagues, and choosing to build my own projects. Those experiences shaped my decisions; another person’s constraints and opportunities may lead to a different path.
