The free version of Skype is great for personal use, but you can also get work done with it as well. I took part in numerous job interviews over video chat during my last year of college. When I landed an internship, we used it to communicate around the office.
But for big work done by big companies, there's Skype for Business. It comes with extra perks such as the ability to chat with up to 250 people and integrate everything with Office. The enterprise-oriented service replaced Microsoft Lync on desktops when it launched at the end of last year.

Back in December of 2011, Microsoft released the first version of Lync for Android, which brought real-time Exchange collaboration to mobile.

Thankfully, Microsoft just released Lync 2013, which brings a nice looking Holo-meets-Windows-Phone sort of UI along for the ride.
The app essentially retains all the functionality of the previous version, allowing you to IM, collaborate, and video chat with other colleagues using Lync.

In a nutshell, it's an IM/contact management/VoIP client used for Exchange - think MSN Messenger with a GTalk twist built for the corporate environment .
The Android version allows you to see your colleagues' availability on-the-go, as well as initiation an instant message, email, or phone call directly from the app. You can also connect to Lync conference calls quickly and easily - no passcodes or conference numbers required. Read More
