Is H1b cap exempt eligible for interview waiver?

Hi,

My husband is applying for h1 b under cap exempt this year 2016. The employer and the location is same as the previous h1b, but his job role is different. His previous h1b was expired in October 2014. Me and my kid also travelled to US with him Under h4 visa. Is he eligible for Dropbox facility or should we go for the interview?

For dropbox eligibility, your previous visa should not have expired more than 12 months ago. When did the last H-1 and H-4 visa stampings expired? Also, was any 221g issued during previous stamping experience?
