Get a free account on Pramp. A community-driven mock interview platform. Based on the criteria you define, Pramp pairs you with another student, and you interview each other’s turn.
Pramp has a built-in video and audio conferencing system so you don’t have to exchange your Skype account or anything.
There is no guarantee who your interviewer/peer will be. What his/her level of experience is. This is why I recommend first Hired.com over Pramp.
Back in 2017, I was fortunate to meet amazing people on Pramp. Including someone else who was also interviewing for Amazon, Axel. We would meet every week to discuss our progress and interview each other. Like accountability partners. We both nailed our interviews and compared our offers. It helped me negotiating my final package.
