Altimetrik interview questions

Synova is currently known as CBSI Global. They called me up and discussed an opportunity with their client IBM. Interview was done at IBM, Calcutta office. Two rounds of interview, written and face-to-face. Was selected for the post. But Synova did not come out with a proper offer letter. They didn't want to put anything in writing and almost forced to accept the offer. Asked for an original document. I didn't accept the offer.

there were two telephonic rounds and there were , 2 written,and it was followed by 2-3 face to face rounds where they asked about java, data structure, algorithms of ok level.
