Google co-founder Sergey Brin's estranged wife told of her happiness with her family life a little more than a year before her very public separation from the tech executive who is now said to be dating a 27-year-old employee. 

In May of last year, Anne Wojcicki was interviewed by a business writer for the blog Inc.com, in which she talked at length about her responsibilities as a wife, mother as well as a full-time worker.

Yesterday, a spokesman for the couple announced that Brin and his wife had been living apart for several months.

The comments by Wojcicki come as it was also revealed that Brin's mother-in-law wrote a series of posts on her Google+ page just before the separation became public - which could be taken as cryptic.

Wojcicki, 40, who graduated from Yale University with a biology degree and launched the DNA testing kit firm 23andME in 2006, offered an idea of what a typical day in her life looks like.

The mother of two, whose happy son and daughter were three and seven years old at the time, told the reporter how she tries to leave the office around 4pm every day to spend time with her brood. 

‘Sergey and I like to have dinner together as a family, usually around 6,’ she said. ‘Then we'll put the kids to bed, and both of us will work until 11pm.’

Wojcicki went on to say that once a week she might stay at work late.

‘It's sometimes very efficient to work until 7 p.m.--and then come home to kids who are clean and ready for bed. Those days are good,’ she said.

The entrepreneur also shared that she enjoys spending time with her extended family, including her in-laws, Brin’s parents.

‘My perfect weekend is going for a walk with my family in the park. I don't think there's anything better,’ she was quoted as saying in the story.  ‘It's funny; everyone talks about a bucket list, but I don't really have one.

‘I did a lot of fun things before I had kids--I traveled a lot. Now, I just really love being with my kids.’

Anne Wojcicki’s account of her life presents a portrait of a contended wife and mother who likes nothing better than to hang out on her ‘nice’ couch and go out for a cup of good coffee with both her kids tucked into a large backpack.

‘I don't really crave much more than that,’ she concluded.

In her ‘day in a life’ account published May 29, 2012, under the title ‘The Way I Work,’ Wojcicki also shared many details about the inner workings of her company, and her role in it.

Wojcicki started the DNA testing venture in 2006, one year before she and Brin got married. The company has raised $68million in venture capital, has 70 employees and nearly 150,000 paying members. 

In the introduction to the piece, blogger Liz Welch wrote: ‘Wojcicki constantly pushes her team to focus on big goals, develop new ideas, and--something that may not come easily for scientists--socialize.’

Then-38-year-old mother-of-two gave a run-down of a typical day in the life of the Wojcicki-Brin household, beginning with a 6.30am wake-up.

After exercising and dropping off her son at his day care, the busy mom would stay in a nearby café until noon, working on her laptop and iPad.

‘I find that I'm more productive at the café, because at the office I spend a lot of time chatting,’ she explained. ‘I think it's important to have flexibility to work wherever is best for you.’

Not surprisingly, Wojcicki noted that she and her co-workers run their company using Gmail, Google Calendar and Google Docs.

Meanwhile, Anna Wojcicki's mother, herself an avid Google+ user, shared a couple of posts on her account shortly before it was announced Wednesday that her daughter had separated from Brin several months ago, and that the tech mogul is now dating a 27-year-old employee.

Just before 4pm Wednesday, Esther Wojcicki shared a link to a story about the downfall of former Disney and Amgen executive Richard Nanula, who has been charged with sexual harassment after allegedly posing as a porn star called Mr. Rich.

Sergey Brin's mother-in-law supplemented the link with a comment that read: 'Sad and shocking to see how he has ruined his life.'

About two hours earlier, the veteran journalism and English teacher who has been working with the organization Learning Matters, wrote on her page: 'Sounds like idea to focus on the present and future and let go of the past.'

The comment was in reference to an article in the Wall Street Journal titled 'What's you type: past-positive, present hedonism or present fatalism?'

Of course, they could be completely unrelated to what was happening in the Brin marriage, but the timing is intriguing.

Since Brin's separation from his wife was made public late last night, more information has emerged about the Silicon Valley titan's new paramour, the British-born Amanda Rosenberg, 27, who left London in search of fame and fortune with Google.

There is no suggestion that the pair became an item before Mr Brin’s separation from Miss Wojcicki.

Only last year, Rosenberg was so friendless after moving to San Francisco that she spoke of eating her lunch alone in the toilets.

Google has been rocked by talk of the romance, and a spokesman yesterday confirmed that Brin – one of the world’s richest men with a $22.8billion fortune – has for several months been living apart from his wife of six years, the mother of his two children.

If they divorce, Californian law suggests their massive fortune would have to be halved – although they reportedly signed a strict pre-nuptial agreement.

While the internet was agog with talk of Brin romancing his much younger employee, the Daily Mail tracked down a distinctly unsurprised former boyfriend of Miss Rosenberg – who said she ‘knew the power of her womanly ways’.

Ewan Butler, 28, a trainee teacher living with his parents in Darlington, said: ‘Amanda’s a good looking girl, and she knows she is. 

'And she’s good at “playing” men – she played me.’

Brin’s relationship with Rosenberg emerged only yesterday – but the pair were pictured together earlier this year at a New York Fashion Week event, both wearing the controversial Google Glass computerised spectacles for which she is marketing manager.

An employee of Google since she graduated with a communications degree from Leeds University, she initially worked for the internet giant in London before last year moving to San Francisco to work at its Silicon Valley nerve centre.

She soon won a role promoting Google Glass, widely criticised as the glasses which enable users to film and broadcast over the internet everything they see non-stop, worrying privacy campaigners.

Miss Rosenberg wrote an online blog soon after she arrived – describing herself as a ‘misanthropic Brit struggling to come to terms with Californian optimism’.

She wrote: ‘I’d been living a beautifully choreographed life in London for pretty much my entire life; family, friends, job, life. Then one day I realised the beauty had faded.

‘So I applied for a transfer with my company to a different country. Yes! The romance of a transfer!

‘Luckily for me this all worked out like I dreamed it would...NOT. Of course it didn’t work out like that!

‘I remember having conversations with people about moving countries, and no one talks about how it felt to be alone. 

'I wanted to grab them and scream “Why are you not telling me about how you ate lunch in the toilets at work for the first week because no one talked to you?”.’

Miss Rosenberg, who previously lived in Wimbledon, adding tellingly that her first thought in her new office was: ‘Hello new boss, hello new team...LIKE ME IMMEDIATELY.’  

A RELATIONSHIP RIDICULED

Sergey Brin, 40, is being roundly mocked on the internet over his apparent relationship with Amanda Rosenberg. 

One of numerous websites ridiculing the reported affair draws particular attention to his recent enthusiasm for the ‘Google Glass’ computerised spectacles. 

The website jibes: ‘Since Google Glass launched the company’s co-founder, Sergey Brin, hasn’t been spotted without a pair. 

'He’s placed himself atop the privacy-eroding project, publicly, and inside Google’s secret labs. 

'Maybe it’s because he’s f****** the Glass marketing manager, Amanda Rosenberg.’

The blog goes on: ‘Knowing that one of the most vital, powerful men at the company has been using Google’s most ambitious product as a dating pool won’t be smooth news for the rest of the team.’

She also wrote that she was initially so shy she failed to turn up at her first work drinks invitation, fearing she would be ‘the weird loner in the corner’, so stayed in eating biscuits alone on her sofa instead.

In an internet profile Miss Rosenberg wrote of herself: ‘I’m part of the master race that is the Chinese Jew or Chew, if you will. 

'Born in Hong Kong but bred in the UK. A misanthrope who’s bad at maths, so I got the worst of both worlds.’

Elsewhere she declares that her motto is: ‘He who hesitates is a damned fool.’

Miss Rosenberg is understood to have an English father and a Hong Kong Chinese mother who worked as an investment banker.

After leaving Marlborough, where Pippa Middleton was two years above her, she soon began a year-long relationship with fellow Leeds University student Mr Butler.

Told his ex was being linked to the Google tycoon, he said: ‘It wouldn’t surprise me in the least – she’s that kind of girl.’ 

He added: ‘Although Amanda did have a posh crew she knocked around with she wasn’t stuck up like you might expect from a Marlborough girl. 

'With me I think there was a fascination with me being northern – I was pretty much the only person in our student halls who went to a comprehensive.’

Intriguingly Miss Rosenberg had already had a high-flying Google boyfriend in America – senior executive Hugo Barra, who recently announced he was leaving to join a Chinese computer firm.

Last night Miss Rosenberg – who got her Google Glass job after coming up with the voice command ‘Ok, Glass’ to activate the device - could not be contacted for comment.

A spokesman for Brin – who founded Google with Larry Page in 1998 – said that he was not legally separated from his wife and that ‘they remain good friends and partners’.

Questions have also been raised about whether the relationship has violated the company's code of conduct, which warns that any romance that creates a conflict of interest could result in those employees being sacked.

The code, posted online, says: 'If a romantic relationship does create an actual or apparent conflict, it may require changes to work arrangements or even the termination of employment of either or both individuals involved.'

The code then asks any potential paramours to consider the following: 'When faced with a potential conflict of interest, ask yourself: would this activity harm my reputation, negatively impact my ability to do my job at Google or potentially harm Google?

'Would this activity embarrass Google or me if it showed up on the front page of a newspaper or a blog?

'If the answer to any of these questions is "yes", the relationship or situation is likely to create a conflict of interest and you should avoid it.'

Google did not respond to calls from the New York Post for comment on the relationship or whether it violated any corporate ethics code.
