Behavioral Technical
After my CV was screened, I had a general 20-minute interview with HR. They gave me about 3 days to prepare for the next round, which was all competency-based questions, and honestly, there wasn't much to it.

Technical Coding
I went through a hiring process run by the external recruitment agency (H&P), and honestly, it was pretty bad. They weren't clear with communication, sometimes even rude, and they really couldn't stick to their own deadlines. When they wanted an interview, it had to be right away, but they were the ones causing delays. For example, a coding interview got pushed back because the interviewer and HR messed up coordinating. In the end, I got conflicting feedback. At first, they said my performance was great and my tech skills were solid, but then they rejected me saying I wasn't technically good enough. This inconsistency, plus their unprofessionalism with deadlines, just left me annoyed and not impressed. The whole thing felt like a waste of my time. The coding and technical questions they asked during the interviews were straightforward and practical.

Technical Coding
It was a 3.5 hour in-person interview with 4 interviewers, each taking about 45 minutes. The office setting was more relaxed compared to dynamic environments, and the average office space was comparable to my current company's new building in NYC. They didn't take me to lunch, so I was hungry until 1:40 PM. One interviewer mentioned that as a public company, they don't spend too much on employees, which gave me a certain perception on the first visit.

- Can you explain what a virtual destructor is?
- Which UNIX signals are unblockable?

Read report →“Given a text file listing city pairs that indicate possible travel between them (e.g., "Philadelphia,Pittsburgh"), write a Java program named Connected. This program should accept a filename and two city names as command-line arguments. It needs to output 'yes' if there's a path between the two cities based on the connections in the file, and 'no' otherwise. Consider that the file defines edges in a graph where cities are nodes. The program should be efficient for large files (assuming they fit in memory) and not crash on malformed input. A city not mentioned in the file is not connected to any other city. Also, provide instructions on how to build the program (like a Makefile) and package the source files (tar/zip). Note that the program must handle connectivity graphs with more than two edges and be production-ready.”
