Had a final round interview. The interview had three interviewers: one for technical skills, one for code design, and one for behavioral assessment. Overall, the experience was good. The interviewers were nice and willing to offer a little help when I was stuck.

Technical:

What data structures would you use or how would you model a banking system for bank customers?

How do you remove all zero subtrees from a binary search tree? (Nodes that are zero but have non-zero children will not be removed. However, nodes that are zero and have children, and down the entire subtree is also zero, should be removed.)

Given a regular linked list with an additional second pointer pointing to any other node in the list, deep copy that list.

Design:

How might you increase security through a coding design for the bank?

Behavioral:

Tell us about a time where you explained something technical to someone that knew nothing about the topic.

Tell us about a time when you learned something on your own and what did you gain from that experience?
