Note that you're expecting the "failure" (and you'll see your instructor's hand reaching for the mixture) so there should be no "surprise" time (unlike real life):
- you keep the aircraft straight with normal controls (primarily rudder) and notice the failure - 1 second
- mix, pitch, power UP - one hand, one second
- identify "dead leg" - one second
- confirm by closing throttle - one second
- identify and pull the pitch to feather - one second
- then check gear & flaps & blue line
with minor variations in order depending on the aircraft (check your POH & SOPs).

That makes it about five seconds - I wouldn't care if it takes a little longer as long as the aircraft is flown for good performance (blue line), no significant loss of altitude, and you don't take the wrong engine!

For average small & medium twins, you should be able to do that quite mechanically and without loosing any altitude. If you are loosing altitude, or getting below blue line, then I don't want my family in the aircraft with you - because real engine failures do happen.

And Tarq57, Lose an engine below about 500-1000... I absolutely agree - got to be familiar with your aircraft and should have a "committed" height nominated - below that, you're going to land somewhere.

Too all up-and-coming multi-engine pilots - you're moving into a more serious regime - bigger, faster, more powerful aircraft with more pax. You've got to learn from other people mistakes because sometimes you'll only get one chance. So be very familiar with some kind of take-off briefing, Vmc, sensible initial climb attitude & speed, after T/O decision point, before landing committed point, actions to perform on engine failure before & after decision point. There are a couple of quite good multi-engine books, available at more pilot shops. If your instructor doesn't know & stress these things, find another one.
