Currently in SB. Got a call from SB HR that 2nd interview went well , went through the benefits and offered salary. She mention she will call my current HR for reference check first. they already called my references (ex-company) to check before shortlisting me to 2nd round interview.

Worried if the job dosent go ahead - I will be in bad books by my current org. This happened to my colleague. Is this the case for SB?
