Had a couple of chats over phone and Skype. Then, I got a take home challenge. It's nothing out of the ordinary, though there is some ambiguity you need to take care of. I didn't continue in the process and they gave me awesome feedback of why it was so. However, some things could be improved. As feedback to Teralytics: work on giving positive feedback (all I got was non-constructive, seemingly forced, "he knows Scala") and balance it with negative (this was way better). On both types of feedback, strive to give examples - without them, some of the points will be vague. Overall it was very pleasant and all the people involved treated me very well.
