During last 3 years HR called me and took 10-15 interviews, every time the lady and there VP sales or Ops head took interviews and try to find out our current companies clientele in deep and they always asked for client name and point of contact details and they never turned back with interview feedback or any selection process either it can b a BDM or any senior managing profile. As per my understanding in last 3-4 years this is purely a lead generation activity by way of interviewing the different-2 candidates from different-2 locations. My suggestion do not entertain there HR or any senior person.
