If I search "plumber" the first 3 results are ads.

I'm not sure why my personal results are often so much better than posts like this one whenever I do the experiment - maybe it's based on location?

Given the reason for office closures was covid, I'd guess that companies in the same geographical area would make similar decisions about when it was appropriate to return to office work. It would be more surprising to me if large companies with similar decision-making throughout the pandemic, in the same geographical area, had drastically different timelines.

If you check their profile their site suggests that have ~15 years of experience.

Yes, absolutely. Men are generally treated very poorly if they choose to voluntarily work with small children.

Or (3) because a huge proportion of perceived performance is subjective. I can't find a study right now, but e.g. http://fortune.com/2014/08/26/performance-review-gender-bias... make a decent argument towards women receiving qualitatively different performance feedback to men.

Slightly tongue in cheek (since Google obviously uses javascript), but Java :)

I believe that the justification for that is that you'll often want to do e.g.

    while (node) {
      node.val += 3;
      node = node->next;
    }

    while (std::cin >> x >> y) { ... }
