Applied online, next day got an email requesting a technical phone screen. Phone interview was one week later. Interviewer seemed annoyed and terse from the beginning. Began to introduce himself and described his past work, during intro asked me to explain how compilers work. Moved on to a technical question. He spelled out a tinyURL link that sent me to an online shared editor, kobra.io. He explained the problem. I asked a clarifying question, then began to jot down a note planning how I'd tackle the solution. Almost immediately after starting to plan a solution, he warned that I should start coding or I'd spend all my time planning. I said okay, and began to write a trie structure in Python. He said that no candidates had been able to complete a solution with a trie in the interview time and urged me to write a simpler solution. I said okay, and wrote a solution that used a stack and a dictionary. Finished the solution, found and fixed a bug where I'd typo'd a variable name. I asked if I should begin cleaning up the code and optimizing, possibly implement a faster solution. He said that wouldn't be necessary, asked if I had any questions for him. Asked about the company culture and workflow. Interview lasted about 45 minutes. Two days later I got an automated email informing me they would continue with other candidates.
