Narrative:
We were in a non standard large transport that is exchanged with XXX airlines (I'm with YYY). We were an inexperienced crew. I was flying the aircraft and the captain was handling the radio calls. Another aircraft on the frequency had a similar call sign (we were abc he was def). We received a descend to 7000 ft out of our cruising altitude of 11000 ft (or so we thought). Actually, descent was given to def although we answered the call. Other contributing factors were: non standard approach vector off the VOR. Non standard radio set up in aircraft. WX was thunderstorms and heavy rain showers. Altitude set was in a non standard location.
