I applied online, and several months later was invited to take an online coding challenge. The online coding challenge was objectively the most difficult interview challenge I've ever had (Eventbrite, Intel, Bloomberg, Qumulo, Zappos, Rakuten). You are required to decipher a template that has been prewritten, and then iterate through an iterator of iterators, and search for a particular target string within the string returned from your iterator. I scrolled down to look at the source code below the editor, and whoever wrote it had written in the comments "crazy hack to build iterators".
The next challenge was just a run of the mill parse text and find the URL type challenge, which can be solved with a dank regular expression. You are given about 45 minutes to solve each of these challenges. You can use C++, Java, JavaScript, or Python.
