Interview Preparation Tips
I applied via referral in Deloitte USI but to save their referral bonus (I guess), they rejected my profile on the portal and called me through Naukri.com. When I asked them the reason, they said its for a different profile them. however it was for the same one.
Also on their career site, it was not mentioned that role is of fixed term hire (for 2 years), but HR disclosed it later, during the conversation. (another discrepancy)
During my initial conversation, HR clearly said there won't be any night shifts and I would have to work from client's location in Gurgaon office. Although it is 2 year contractual role.
But during my technical interview, the person clearly said to me that I would have to relocate to Bangalore for working from client's secured ODC in office. Also there would be rotational/ night shifts (without any extra pay). Basically they were looking for someone who would devote his 24X7 time to the company for a minimal salary and does not demand for work life balance or weekends off
Neither the HR nor the interviewer opened their web camera during the video call. But HR kept asking me to keep my camera open, even during the waiting time
