29 Toughest Questions Asked in Facebook Job Interviews

Zuckerberg created Facebook
11 years ago with an aim to
connect the college students.
Today, apart from connecting the college
students and obviously many others, it's
one the favorite places to work at in the
tech industry.
The interns working at Facebook make
$25,000 more than the average US
citizen. Also, the employees on Glassdoor
voted Facebook as the #1 company to
work for. But, getting a job there isn't an
easy job. To accomplish that, you'll have
to answer some tricky Facebook interview
questions to prove your caliber.
Most of the questions are inclined

collected some of the toughest questions

Windows 10 now on 600 million machines.

Microsoft CEO Satya Nadella told shareholders that Windows 10 has now passed 600 million monthly active users, picking up 100 million since May of this year. This number counts all Windows 10 devices used over a 28-day period. While most of these will be PCs, there are other things in the mix there: a few million Xbox Ones, a few million Windows 10 Mobile phones, and special hardware like the HoloLens and Surface Hub. The exact mix between these categories isn't known, because Microsoft doesn't say. The company's original ambition (and sales pitch to developers) was to have one billion systems running Windows 10 within about three years of the operating system's launch. In July last year, the company acknowledged that it won't hit that target—the original plan called for  50 million or more phone sales a year , which the retreat from the phone market has made impossible. But at the current rate it should still be on track for somewhere in excess of 700 million use...

But that’s not to say that it  can’t be –one of the best ways to start your empire is with an Amazon affiliate plugin. For me, the Amazon Associates program has been one of the biggest earners for me over the years. Not only are there CPM ads like Google Adsense (you know, the normal banner ads we all love to hate), but any time someone clicks a link from your site, you get a percentage of  anything  they buy while the token from your site lasts in their browser. If they buy a song, you get a few cents. If they buy a new MacBook Pro and iPhone? You get…a lot more cents. With that in mind, WZoneLite is a  pretty cool WooCommerce Amazon affiliate plugin that syncs everything together s...

Game-changing SEO trends that will dominate 2018.

Changing nature of the rules of the game. As search engines strive to improve the quality of search results, some ranking factors shift shapes, others fall into oblivion, and completely new ones arise out of nowhere. To help you stay ahead of the game in 2018, here’s a list of the most prominent trends that are gaining momentum, with tips on how you can prepare for each. 1. The rise of SERP features Are you assuming a #1 organic ranking is  the  way to get as much traffic as possible? Think again. Increasingly, SERP features (local packs, Knowledge panels, featured snippets and so on) are stealing searchers’ attention and clicks from organic listings.
