I was referred by a friend who works at IBM.

My interview was scheduled within 15 days of job acceptance. I was interviewed on November 17, 2016, at the Mindspace office in Hyderabad.

The first round was technical, conducted telephonically inside a conference room. It took around 30-45 minutes.

After that, I was called for a PDM round, which was also telephonic. Following selection in the PDM round, they asked for a video conferencing round where normal conversation occurred.

I was selected for the post and was informed by the recruiting HR by saying, "You have been selected."

Then, they asked me to fill out certain BGV (Background Verification) check forms and to attach all documents via email within a week.

However, it has been almost a month post-interview, and I have not yet received my offer letter.

They asked more on project scenarios and big data ecosystems.

Questions were not that tough, but you should have knowledge on everything.
