How Did You Prepare For Interviews

This is a very relevant question. FAANG interviews are like binary — either you qualify mostly all or you qualify none. The preparation depends on:

  • Your understanding with computer science fundamentals – This includes data structures, system design, topics from OS viz. threading, scheduling, memory management and networking concepts like IP address, DNS and request-response cycle. If you are interviewing for an HFT, the focus is majorly on OS and networking.
  • Your projects – The projects you do gives direct visibility to your understanding of computer fundamentals.
  • To prepare for point 1, practice “regularly” on leetcode.com and interviewbit.com . If you are not confident in data structures, a course from coding institutions will help surely if you practice. Once you are confident, start practising company-wise. The timeline should not be more than 3 months for confident aspirants, 8 months for new to algorithms. If you are taking more than that you are doing injustice to yourself. Sports Programming is NOT required for most FAANGs.

    For system design, “Grokking the system design” is the gold standard for preparation. Just reading the content didn’t work for me. I practised system design on a fantastic peer-to-peer interview platform pramp.com.

    How To Prepare For An Interview :

    You have to learn 2 languages c and c++

    Step 1:Before starting the program you have to complete an Aptitude .so the first start with apps and then move to Codings

    The best 3 Platform to learn codings

    Step 3: Have to learn interview-based coding projects

    Those three steps you have to follow.

    Interviewing Is A Skill

    During my preparation, I always knew that interviewing would be challenging. But I honestly had no idea how hard it would be until I was knee-deep into my first interview.

    In the lead-up to the interviews, I had used both paid and free services, which simulated coding and whiteboarding interviews over the phone with people who had industry experience interviewing candidates. Those practice interviews were essential for priming me for the pressure involved. But as I later realized, they only amounted to a fraction of what a real interview consists of.

    Id advise against interviewing at your dream job without having a few mock or real interviews under your belt. The nervousness can be incredibly overwhelming, and it can only be dulled through practice.

    As with many other things in life, practice will improve your confidence.

    Simple Tips On How To Crack An Interview For Your Dream Job

By doing the research you will get the knowledge to answer questions like: Tell about our company? who are our competitors? What are our products? etc.

    2. Reach early to the location: Punctuality is very important for the interview. Being timely are a few things you must to practice in the standard of living because it can help you always. Reach ten to fifteen minutes early so that you can relax and ready to give the interview.

    3. Dress formally and with neat hairstyle: Neatly comb your hair. Men must always shave before participating in an interview. Use a soft perfume or deodorant. Men should be dressed in smart formal clothes such as well ironed trousers and shirt with a tie or formal suit and wear a formal belt and formal watch. Combination of white shirt and black pant work well, make sure your shoes are polished.

    Women, on the other hand, it is not essential to wear western clothes. Women must be dressed in non-fussy and dignified clothes such as salwar kameez, sari or trousers/skirt suit.

    9. Finish the interview on a positive end: Say Thank you to him/her for giving such a valuable time. Ask them if you want to know any further information about the work, culture and etc in their company. Ask for the feedback it gives a positive impression on you but does not overdo it.

    Do Coding Interview Questions While You’re Learning

    Cracking the Facebook Coding Interview

    THIS IS VERY IMPORTANT.

    Start doing coding interview questions while you’re learning data structures and algorithms.

    You need to apply what you’re learning to solving problems, or you’ll forget. I made this mistake.

    Once you’ve learned a topic, and feel somewhat comfortable with it, for example, linked lists:

  • Open one of the coding interview books
  • Do 2 or 3 questions regarding linked lists.
  • Move on to the next learning topic.
  • Later, go back and do another 2 or 3 linked list problems.
  • Do this with each new topic you learn.
  • Keep doing problems while you’re learning all this stuff, not after.

    You’re not being hired for knowledge, but how you apply the knowledge.

    There are many resources for this, listed below. Keep going.
