The interview was pretty decent. I've only had the initial recruiter phone call and a technical assessment so far. I expect to move on to the next round. Here is the question: # /* # we're going to build an event counter # // increments the counter associated w/ event_name at the given time # // time is given in seconds from the epoch # record(event_name string, time int) # // resolution is either hour or day # // start and end are inclusive / exclusive respectively # // if there aren't any events for a queried hour/day fill the array w/ 0 # query(event_name string, resolution string, start int, end int) []int # record("/api/v1/products", 0) # record("/api/v1/products", 1) # record("/api/v1/products", 3600) # record("/api/v1/products", 24 * 3600) # query("/api/v1/products", "hour", 0, 3) -> [2, 1, 0] # query("/api/v1/products", "hour", 36, 48) -> [...] # query("/api/v1/products", "day", 0, 3) -> [3, 1, 0] # */
