Perguntas de entrevista da empresa Heyzap

I applied online after clicking through a who's hiring post on Hacker News and submitting my resume and cover letter online. I was contacted the next day for a technical phone screen with one of the founders. When we talked on the phone, he started by asking me about projects I had built and technology that I had used and my ideas and motivation behind that. I discussed a web site that I had built and he asked me questions about web site performance and scaling and what techniques I would use to speed it up. I discussed caching and sharding in response. He then asked me details about the differences between programming languages and my preferences and understanding. I contrasted C and Python and discussed Python implementation details. He then asked me code a fibonacci number function (input n, output nth fibonacci number). I was nervous and wrote up an extremely naive recursive implementation and then struggled a bit with the the iterative implementation, but got through it with some prompting. After this, I was given a work sample problem to make a log parser that took data in their production log format and total unique visitors to certain url paths and also do funnel analysis on certain paths. I was told to write it in any language and I chose Python. They wanted to make it extensible, so I wrote some generic log-processing functions that took lambdas that did that actual computation specifics so all of the processing could use the same framework. In addition, I made the input format of paths be regular expressions to be matched. I don't recall precisely but I think this took three or four hours. Finally, I had a culture fit interview with the other co-founder where we discussed my general interests and the culture of the company, emphasizing the need to learn quickly.

Email exchanges were very curt and uninformative. The interview process itself was unnecessarily long and didn't focus on finding a connection between my skills and the position. In other words, it was a great experience for me to determine whether a company is worth working for--which in this case its not.
