How to implement an Atomic property wrapper.
given an API that looks like this: interface EventReporter { enum Interval = {SECOND, MINUTE, HOUR}; public void recordEvent(String eventName, LocalDateTime t); public Map<String, Int> getEventCounts(String eventName, LocalDateTime start, LocalDateTime end, Interval i) } and data that looks like this: "x", 20:00:01 "x", 20:00:01 "x", 20:00:15 "x", 20:10:00 "x", 20:58:00 Describe a data structure and how you might implement the API's that come up with counts (via the "getEventCounts") for these three different "interval" types: Ask for event counts for "x", from 20: to 21:, with interval Second, you'd get: {"20:00:01": 2, "20:00:15": 1, "20:10:00": 1, "20:58:00": 1} Or with interval Minute: "20:00" -> 3, "20:10" -> 1, "20:58" -> 1 Or with interval hour: "20" -> 5

Sorry, I can't remember the details, but I think the first one was just asking questions that would verify my resume. The second asked some extremely simple questions on HTML and JavaScript
The phone interview question was done via Coderpad and was titled "The Threebonacci Table" For the purposes of this problem, a Threebonacci sequence is a twist on the Fibonacci sequence where you would sum the previous three elements to get the next element. That is, if the Threebonacci function is defined as t, where n is the index of the element involved, t(n) = t(n-1) + t(n-2) + t(n-3). You can assume t(0) = 0, t(1) = 1, and t(2) = 1. With this information, please complete the tableview in the following UIViewController so that each UITableViewCell displays its Threebonacci value corresponding with its row index. An example is as follows: 0 1 1 2 4 and so on so forth.

First question I was handed a laptop with Xcode running on it. The assignment was to write a super simple browser app that used substitution (or "regular expression", as the interviewer referred to it) to replace any instances of the word "Nest" with something arbitrary (e.g. I chose something like the name "Glassdoor").
