There’s no doubt Google’s office culture is now very different to what it was like back when they first began hiring employees.

Founded in September 1998, only six of Google’s original 21 employees are still at the company – and that includes founders Larry Page and Sergey Brin.

But since launching their careers at the multinational technology company, some have gone on to become entrepreneurs, whilst others have become angel investors and top executives at other tech companies.

Some are even retired, reports Business Insider.

Here are five of the most interesting:

1 – Marissa Mayer joined Google as a software engineer, then became CEO of Yahoo.

Employed by Google: June 1999 to July 2012

Most recent position at Google: Vice president of local, maps, and location services

Current company/position: Mayer served as CEO of Yahoo from July 2012 until June 2017, leaving the company after the completion of Yahoo’s sale to Verizon. These days, Mayer is keeping a low profile, though she recently testified before Congress about about Yahoo’s massive 2013 data breach.

2 – Jim Reese was an engineer at Google.

Employed by Google: 1999 to 2005

Most recent position at Google: Chief operations engineer (and “Head Neurosurgeon” — he was a physician before coming to Google and jokes on his LinkedIn that he performed frontal lobotomies on Thursday mornings only). He was once knocked out by a 200-pound metal beam in Google’s leased data center.

Current company/position: Reese currently serves as a board member for Spark Program — a career exploration program for middle schoolers — as well as an advisory board member of Harvard Medical School’s Department of Biomedical Informatics.

3 – Amit Patel was a top Google engineer and helped come up with Google’s unofficial slogan, “Don’t Be Evil.”

Employed by Google: 1999 to unknown

Most recent position at Google: Though we couldn’t find Patel’s most recent title, Steven Levy’s book “In The Plex” offers some interesting details about him. Patel was instrumental in highlighting the value of Google’s search logs. He also asked Eric Schmidt if he could share his office, shortly after Schmidt had joined the company as CEO (Schmidt said yes because he thought it would be “un-Googley” to say no).

Current Company/Position: Unknown.

4. Harry Cheung was an original Google engineer.

Employed by Google: January 1999 to December 2004

Most recent position at Google: Cheung served as a software engineer at Google. His nickname used to be Harry “Spider-Man” Cheung because he was a “crawl” engineer, monitoring the progress of Google’s spiders as they indexed the web.

Current company/position: These days, Cheung is an angel investor in startups including Caviar, Qwiki, Badgeville, and PrePay. He’s also a founder at Roostify, a home-lending startup.

5. Craig Silverstein was Page and Brin’s first hire.

Employed by Google: 1998 to 2012

Most recent position at Google: Silverstein worked on various projects, including mentoring engineers and serving as technology director. As Google’s third employee, he helped actually build the search engine.

Current company/position: Silverstein now serves as dean of infrastructure at Khan Academy.

Think you will still be at the company you’re working at in 20 years time? Didn’t think so.
