Narrative:

Pilot flying failed to select approach tile when cleared for the approach; the aircraft subsequently failed to intercept the glide slope. The pilot flying and check airman realized the error at approximately one dot above glide slope. The pilot flying initially attempted to intercept the glide slope by disconnecting the autopilot and manually flying to the glide slope. The check airman suggested using vertical speed to accomplish the intercept. The pilot flying reselected the autopilot on and selected vertical speed however he selected too high of a rate of descent. Shortly afterward; the low altitude warning sounded for excessive rate of descent. The pilot flying initiated a go around. On the go around the pilot flying failed to level off as directed at 3000 feet by approximately 400 feet. The subsequent approach and landing was uneventful.failure to select the approach tile when cleared for the approach was the proximate cause of the unstable approach. Attempting to intercept the glide slope from above rather going around upon discovery of the failure to intercept the glide slope resulted in an unstable approach and necessitated the subsequent go around. Not accomplishing go around procedures (selection of flight change; top bug) most probably resulted in the altitude exceedance on go around.suggestion: select the approach tile when cleared for the approach. Go around rather than attempting an intercept from above glide slope. Strict adherence to go around procedures will result in proper altitude level off.

Title: B757 First Officer reported they failed to select the approach tile when cleared for approach; which led to an unstable approach and then had an altitude excursion during the subsequent go-around.
