Too Long; Didn't Read
There are a few additional ways you can get the context you need before the job interview. Read the job description, the skills the recruiter might ask about, and what the company actually wants. For better communication with the interviewer, you can ask what communication medium would prefer like Skype, or Hangout, etc. Test your setup before the interview call and make sure the microphone is pointing at your face when you're in a video conference. Write a list of the key skills mentioned in the company's job description.
