Horrible interview experience with SG. Completed two rounds and told that manager round will happen in next week due to (Manager was on vacation,year end ,blah blah...). But never received a call from them . After two weeks called them and got to know position was on hold. If you are not having vacany why did you conducted the interview?. Simply wasted my whole working day. Guys never attend the interview they will waste your valuable time
