The most important technical specification for a video interview is the internet speed of your network
You have to be careful about the technical part of video interview to have uninterrupted discussion with your prospective employers.

You have to consider carefully the technical aspect of the video interview. The most important technical specification to consider before a video interview is the internet speed at your place of the interview. Also, check the distance between the router and the location to have the best possible internet speed during the interview time.  You can have better internet speed if you are near to the wireless router and speed may slow down if you are far off from the wireless router. Do you have dual-band or single-band wireless router? If you have dual then check the best reliable network. You can get the most speed on 5.4GHZ connection but can be spotty. You can get a little bit less speed on 2.4 GHZ  but it is more reliable. You can check the internet speed by doing an internet speed test to decide which network to choose and where to attend video calls.

Federal Communication Commission recommends internet speed of 1 Mbps for standard personal call and you need 1.5 Mbps for HD quality video call. But when you have more people on the call then they recommend a minimum internet speed of 6 Mbps for HD quality call. You can check the specification given below as a reference to check bandwidth requirement for your video interview.
