Multiple Interviews on same day

Hello. I applied for elitmus business associate job and got a interview call. I applied for webyog and attivo and status for both is applied. I’ve got 45 minutes before time for accepting elitmus interview runs out. I would prefer webyog’s or attivo’s job over elitmus job. So should I accept elitmus interview call? What should I do if I accept elitmus interview and later got interview call from either or both of the companies

i think u should accept elitmus call…bcoz I have received webyog and attivo network interview call for 11th june…so I think u are not selected for both the interviews as interview call has already been sent.

is it necessary to wear formals on the day for the evaluation test ??
