Most if not all russian approach/letdowns look like that - the rectangular racetrack...SVO definately has ILS...
As for manner of approach the airspace around Moscow is very busy with a large number of airports both civil and military in a small area and restrictions as to overflying the centre of the city etc. Also many Russian aircraft that are flying internally still have very basic RNAV capability (if any at all...some still have no DME!)
and so again there is less flexability of approach profile available to both aircraft and controllers alike...
Although full radar approach equipment is in place most approaches/departures seem to be flown to a rigid framework just like a procedural STAR/SID as the controllers are not in a position to use radar vectoring as a 'tool' like their counterparts at European airports...for the reasons above.
