intermediate care vs med/surg floors

so I just got called for an interview for a nights med/surg position. After I got off the phone I got online to look at the positions again and found a day position for intermediate care. Thing is, I dont know what intermediate care is. I dont want to be a critical care nurse and someone told me it is a step down from that. Would it be better to take the nights med/surg position as a new grad or should I ask about the days position for intermediate care during my interview? Is that a big NO to ask about another position during an interview?
when i worked in intermediate care it was also considered cardiac step-down. So we got post-open heart surgery such as cabg and valve replacements, post stents, post MI, post pacemaker. Ocassionally we got some medical tele overflow. I started out in med-surg on evenings. I worked nights in intermediate care. I am not a night person and had to leave. If you feel you can do well with nights, i'd start on med-surg because that experiance is very valuable. It's surprising that an IMCU is taking new grads. Ours required 1 year of med-surg experiance prior.
