Narrative:

We were getting vectored for an ILS approach in IMC conditions. As the pilot flying; I had commanded an inadequate descent rate which resulted in going above the glide slope prior to intercepting the localizer. Upon recognizing this and now on course; I then commanded a greater vertical speed from the autopilot which resulted in us going below the glide slope without the autopilot capturing just prior to the final approach fix. The captain recognized the error and our unstabilized condition; took the controls and executed a missed approach. During the missed approach maneuver; ATC issued an altitude alert for our sink rate. The egpws warning for glideslope was also heard. The missed approach and subsequent ILS approach was completed uneventfully.the primary cause of this event was my errors in decision making resulting in me putting the aircraft in a high and fast situation for which I over corrected. The contributing factors was my lack of experience in this type of aircraft. This situation could have been avoided by slowing down and descending much earlier. When allowed to fly an airspeed at our discretion and expecting short vectors to final; I should have slowed down much earlier.
