Coding Technical System Design
I took a quiz and scored in the 60th-99th percentile. Then, I had a 2-hour interview two days later. The first part involved building a Tic Tac Toe game in the terminal, where I reached step 3/5. Next, I answered general coding questions, which I felt I did well on. After that, I had to debug a web crawler, fixing about two out of five test cases. Finally, there was a System Design question about creating an API for a car catalog. I received positive feedback during the interview, but the results weren't as good as expected, which confused me. Despite that, it was a good experience overall, and the interviewer was nice.

Coding Technical Technical System Design
The process begins with a multiple-choice quiz on a chosen topic like mobile, front end, or general knowledge. My choice likely influences the phone screen. After the quiz, I scheduled a two-hour interview split into four sections: coding, general knowledge, debugging, and architecture design. For coding, I had to build a console app in Python, Ruby, Java, or C, with internet access allowed. The interviewer was mostly quiet. General knowledge covered topics from mutex locks to bloom filters; saying 'I don't know' was an option, but answered questions might have follow-ups. Debugging was tough, involving fixing a web scraper (Python version with 5 files and 4 tests) so tests would pass, testing code reading and debugger skills under time pressure. Architecture design involved designing a car search API (by model, color, license plate) and explaining tech choices. Feedback included strengths, weaknesses, and improvement suggestions. Coding and general knowledge seemed accessible for beginners, while debugging and architecture favored experienced candidates. It was a bit different but worthwhile.
Confirmed questions3 questions
- Can you explain what database indexes are and what advantages they offer?
- What are mutex locks, how are they implemented at the hardware level, and how can a deadlock occur?
- What is the outcome if a C function returns a pointer to a local integer variable that has been assigned a value, and why does this happen?

Coding System Design Technical
So, I did an online quiz and then an online programming test. After that, a recruiter called me. The interview itself was about 3 hours long. First, there was a coding round where I had to build an AI game. Then, some basic design questions were asked. After that, it was a debugging round with a Java crawler code, and I needed to fix it so all tests passed. The last round involved some general questions about my interests. It was a tough but interesting interview. The interviewer was super helpful, especially when I had issues with Maven installation, guiding me through different commands and languages.

Read reports →“Given a string of numbers and a target value, write a method that prints all possible equations formed by inserting basic arithmetic operations (+, -, *, /) between the digits that evaluate to the given value. For example, for input f("323",3), the output should be "3 * 2 - 3".”
Read report →“Given the digits of pi (314159265358), find expressions using operators (+,-,/,*) to reach the first 5 digits of e (27182), keeping the digit order the same. For example, 3 + 1 - 415 * 92 + 65358 = 27182 or 3141 * 5 / 9 * 26 / 5 * 3 - 5 * 8 = 27182. Write a function that takes a list of numbers (as a string) and a target, and returns all ways to form expressions that equal the target. For instance, f("314159265358", 27182) should display results like 3 + 1 - 415 * 92 + 65358 = 27182, 3 * 1 + 4 * 159 + 26535 + 8 = 27182, etc.”
