Entretien

After a recruiter reached out to me via LinkedIn, she gave me a 30 minute quiz where she asked me basic Linux questions.
Next, she directed me to another recruiter who asked me one basic data structures/algorithms based question and then a file parsing question.

    Entretien

    The process begins with an online pre-screening quiz, multiple choice questions about basic OS concepts and Linux tools.

    Then there are 2 phone interviews: coding and systems. Coding round is File I/O and data manipulation. Systems round they give you a troubleshooting scenario and make you drill-down on the topic.

    Finally, the onsite interview consists of four total rounds: 1 behavioral, 1 systems, and 2 coding rounds. Unfortunately, I had a bad day and choked on the coding rounds.

    First part is a 20 question multiple-choice quiz that you have to complete in 18 minutes. The quiz covers basic linux commands, operating systems concepts, and networking. Very basic questions.

    Then its a 45 min algorithm interview over phone, with coder pad. Pretty easy questions. I got goat Latin and dinosaur CSV parsing question.

    The second interview is also over the phone and is an open-ended discussion with the interviewer. He/she asks questions about operating systems and debugging Linux systems. They go deeper and deeper into concepts until you don't know what is going on. Study Operating Systems fundamentals and tools to debug Linux systems (top, vmstat, dstat, sys trace, etc.).

    3 step process.
    First, the recruiter sent a link for a Linux related quiz. These were all related to Linux commands.
    After that there was an Algorithmic Round, in which the questions were pretty basic, Leetcode easy, but the focus was not in complexity but systemic design, and exploring alternate implementations for better feature coverage.
    Third, there was a systems round which was related to Linux Internal and Troubleshooting a system under load. All relevant topics for this round could easily be read up in Brendan Gregg's blog and his book.

    Not sure where I went wrong, was expecting an acceptance offer.

    Entretien

    You first had to complete an 20 question quiz, then a coding phone interview, and lastly a systems phone interview. Afterward, you would get told offer or no offer.

    The 20 question quiz is all multiple choice. You will have 18 minutes to complete it, which means they give you about 54 seconds for each question. Mine were all based on linux and networking, essentially proving that you know your way around the linux shell and are at least competent in networking. A good way to prep for this would be to install linux on your computer (I recommend Ubuntu or Debian) and use it from day-to-day. Try forcing yourself to use the shell instead of the graphical interface. It'll make you much more familiar with how it works and best prepare you for the quiz.

    The phone interviews were the most challenging. In the coding interview, I had two problems. A "warm up" and a "difficult" one. They weren't particularly difficult problems, but if read incorrectly you could easily mess them up. If you take your time and think out loud, you'll do fine.

    The second phone interview was the systems interview, it was very holistically. I wrote no code in this interview and instead got an open ended question regarding real life situations that might occur. One question that is similar to one I got is "'httpd' is not serving files from '/var/www/html'. Why might this be happening? How might you go about diagnosing and fixing this?". Be sure to know exactly where your knowledge ends. If you do not know something, do not waste their time acting like you do. They want to see the breadth of your knowledge, and if you don't know something tell them and they'll move on to something else which you might. It's okay to speculate and apply other knowledge to your situation. For example, "I've used W before on X system and it behaved in Y way. I'm unsure whether or not it would apply to our scenario with system Z, but I would first look into this because of that experience."

    I was basically contacted by the recruiter after a referral. The process was fairly quick with an initial screening quiz, then a phone screen. Unfortunately, I got too nervous and bombed the coding screen.

    2 phone screens (coding and systems) followed by a 5-part onsite interview consisting of coding, systems, networking, design and behavioral. The phone screens are relatively easy. I havent gone in for my onsite interview yet.

    Very welcoming and helpful through every step of the process. The recruiters would always send informative emails about where in the interview process I was and what the next steps would be. All were very professional and prompt. Would interview again!
