Hello Aspirant! IGNOU has it's own campus placement cell. But as far as the number of students in IGNOU is concerned, the placement is negligible. You may not be guaranteed for the placements but anyone who has IGNOU degrees, has the good subject knowledge. If all you want is a degree, then you can go to IGNOU as it is the cheapest.
Hope this helps. All the Best!
