    Application

    I applied online. I interviewed at Facebook (New York, NY (US)) in March 2020.

    Interview

    A recruiter contacted me over email and set up a phone interview for the following week for a 15-minute call. I guess next round would have been with a hiring manager

    Interview Questions

    • PLEASE DON'T TAKE THE PHONE SCREENING LIGHTLY! I did and got rejected. I was expecting SQL questions and in general talk about my resume but she asked me a question on product sense and I was completely unprepared for it. Creation of Facebook user groups has gone down by 20%, what will you do? sounds simple but I messed it up so badly. I was just blabbering anything in an unstructured way, I sounded so stupid and not even fit for a small company forget Facebook. The recruiter was nice and she did not say anything but I were to hear my own answer, I would reject myself on spot. I regret it so much wish I could have prepared for it. I hope someone sees this and it helps them.

      The SQL questions were easy and I did answer them correctly- what kind of joins to get only common rows, what the natural sorting order etc.   8 Answers

    Interview

    Telephonic Interview: 30 mins SQL and 30 mins coding.
    Expectation: 4/5 in SQL should be correct and 3/5 in coding should be correct.

    Most of the folks have already explained this process in detail so will jump on the interview questions.

    Interview Questions

    • want you to write me a simple spell checking engine.

      The query language is a very simple regular expression-like language, with one special character: . (the dot character), which means EXACTLY ONE character (it can be any character). So, for example, 'c.t' would match 'cat' as the dot matches any character. There may be any number of dot characters in the query (or none).

      Your spell checker will have to be optimized for speed, so you will have to write it in the required way. There would be a one-time setUp() function that does any pre-processing you require, and then there will be an isMatch() function that should run as fast as possible, utilizing that pre-processing.

      There are some examples below, feel free to ask for clarification.

      Word List:

      [cat, bat, rat, drat, dart, drab]

      Queries:

      cat -> true
      c.t -> true
      .at -> true
      ..t -> true
      d..t -> true
      dr.. -> true
      ... -> true
      .... -> true

      ..... -> false
      h.t -> false
      c. -> false
      */

      // write a function
      // Struct setup(List<String> list_of_words)
      // Do whatever processing you want here
      // with reasonable efficiency.
      // Return whatever data structures you want.
      // This function will only run once

      // write a function
      // bool isMatch(Struct struct, String query)
      // Returns whether the query is a match in the
      // dictionary (True/False)
      // Should be optimized for speed   18 Answers

    The process took 3+ weeks. I interviewed at Facebook.

    Interview

    **Beware** of this company, it has eroded, lacks diversity and also has low IQ Asian and Indians en-mass working for it now. My initial 45 minute interview was with a Caucasian and went well.

    Initial 45 minute interview with an employee followed by virtual onsite. It was horrible to say the least. While the first 45 minute was with a Caucasian, about 7 people were present in my virtual onsite and 4 were Indians and 3 Asians. There is severe lack of diversity in this company. The average age of the people was also 45 years as I checked their LinkedIn profile. The Indian and Asian will not hire another Indian for sure.
