There were 2 interviews: the 1st was with engineers and the 2nd was with directors. The interviews were not tough. I was a junior so mostly I expressed my motivation, passion and my study about AI and deep learning.

Ask to give them a presentation based on my portfolio for about 30-40 minutes with short Q&A at the end. Interview was relatively comfortable. Provided good summary of what I would be doing once I get in. Asked technical questions while presenting my portfolio.
