First, their existing engineer conducted my telephonic interview, followed by their Business Development Manager (BDM). Then they called me for a face-to-face interview, which started with a technical round including questions as well as two codes in front of both the BDM and the Application Engineer. Then their Director came and asked me a few questions out of which i was able to answer 70 %. Then after lunch had a discussion regarding salary and all happened. Next day, they gave me the offer letter.
