Entrevista
After reviewing my resume they arranged a phone interview. I was contacted precisely on time and spoke to a member of the team I would be working for. The interviewer immediately wanted me to code for him, and provided a link to Google docs to do so. After programming we chatted about the company and I was offered a chance to ask questions. Interview ended positively but I later received a rejection letter.

Pergunta 1
Given two lists, A and B, of sizes n and k, respectively, describe an algorithm to determine the intersection, C, of the two lists. What is the complexity of your algorithm? (The obvious solution is O(n*k)). Can you describe a solution that is faster? (An optimized solution can do it in O(n+k)).
An integer is represented in binary as a sequence of 0's and 1's. Write a function that returns the number of 1's in the binary representation of a given integer.
Suppose you have a system that keeps track of thousands of users' contact information, including email address. This information is stored in plain text, on disk in a hierarchical directory structure (on a Unix operating system) organized by year, month, and day it was entered in the system. Something bad happens and the system crashes. We want to get the email address of all these users to notify them. How would you parse these directories and files to generate a simple list of email addresses?

The whole process stretched over nearly a month, longer than I anticipated. After an initial phone screen, I faced a technical round that included a Min Stack implementation question. We discussed design considerations and thread safety, which threw me for a bit. Fortunately, I remembered a specific mock interview I practiced on PracHub that mirrored this scenario closely, making me feel more at ease. Ultimately, I received an offer, but I chose to decline due to the company culture not feeling like the right fit.
