Bewerbung

Ich habe mich online beworben. Der Vorgang dauerte mehr als 4 Wochen. Vorstellungsgespräch absolviert im April 2017 bei King (Berlin).

Vorstellungsgespräch

I received a test as a word doc and was asked to complete it in 2 hours and send it back as a word doc. It felt a little unprofessional, but HR were at least nice. I didn't get past the test so I assume my answers weren't good enough.

Fragen im Vorstellungsgespräch

  • Question 1. (5-20 minutes)
     A cube is painted Green on all six sides. It is divided into 125 (=5 x 5 x 5) equal smaller cubes.

    Find:
    1.1 The number of smaller cubes having a) 3 faces coloured?
    b) Exactly 2 faces coloured? c) Exactly 1 face coloured? d) 0 faces coloured?
    1.2 All 125 cubes are put into a bag. If a single cube is selected at random from the bag, find probability of picking a cube having 1 or more Green faces
    1.3 What is the average number of Green faces on a cube?

    In the above situation N=5, (with N^3 =125).
    1.4 For general N, give a formula for the number of smaller cubes with exactly 2 faces coloured 1.5 For what values of N is this formula correct?   Frage beantworten
  • Question 2. (5>10 minutes)

    Write a program which calculates the sum of the first 10 Fibonacci numbers that are bigger than 1000.

    You may use pseudoGcode or any programming language you like (Java, C, C++, R, Python, etc) G please state what language you are using. [Note: Fibonacci numbers are the following series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... where each term is the sum of the previous two terms]   Frage beantworten
  • Q 3.1: In SQL, what statement will count the total number of rows in this table?

    Q 3.2: In SQL, what statement will count the total number of rows corresponding to logins on 1st May 2015?

    Q 3.3: In SQL, what statement will count the number of unique customers?

    Q 3.4: In SQL, what statement would be used to create the above table (without any data in it).
      Q 3.5: In SQL, what is the difference between an inner join and an outer join? Please give an example of some circumstances where you would recommend to use an outer join?   Frage beantworten
  • Question 4: (5>10 minutes)

    The chart below represents the distribution of play time in a day, for a sample of our players. The points a, b and c mark the values of three measures used to summarise the data.

    Q 4.1: What standard measures are a, b and c most likely denoting? Please explain why. Q 4.2: If you drew n samples from this distribution and measured their mean, then repeated that many times, how would you expect the distribution of those sample means to differ from this distribution? Q 4.3: Would its standard deviation be bigger, smaller, or the same as this distribution's standard deviation and why?   Frage beantworten
  • Question 5: (20>50 minutes) (suggest you read the whole question before starting on it)

    SITO elevators have a system to simulate different elevator control mechanisms in their buildings. Let us assume a building has M elevators and N floors.
      You are in charge of measuring the performance of different elevator control mechanisms and so will need to design the data model to capture observed data and the measurements you would calculate on that data model. Assume a typical simulation run proceeds over a 24 hour period and you are allowed to observe as much as you like (when/where each elevator is, how many passengers, where the passengers are, when/where they arrive/depart, etc – if in doubt assume you can observe it). From your detailed data model you will then need (with very simple calculations) to determine various performance measures, for example:

    • Average waiting time per passenger • Average journey time per passenger • ... etc

    Q 5.1: List the different stakeholders who would be interested in elevator performance (a “stakeholder” is any person or group who have an interest in or may be affected by some aspect of elevator performance).
      Q 5.2: List other performance measures that it would be useful or important to measure – make sure these cover all of the stakeholders. (Hint: there are lots and lots of these. Aim for 10 or more...).
      Q 5.3: What would a suitable data representation look like? Please design a series of tables (as would be suitable to put in a database or spreadsheet). Make sure that the data representation (with very simple arithmetic calculations) is adequate to calculate the above measures, and any other measures that you deem important (and that those
    calculations are fairly easy and unambiguous). Please point out any problems you might expect to arise with your data model.
      Q 5.4: For “Average waiting time per passenger” and at least 2 other performance measures, describe how they can be easily calculated from your data model. Preferably write the SQL code you would use to calculate the waiting and journey times.   Frage beantworten

    Bewerbung

    Ich habe mich auf Empfehlung eines Mitarbeiters beworben. Vorstellungsgespräch absolviert im April 2016 bei King (Stockholm, Stockholm (Schweden)).

    Vorstellungsgespräch

    The interview process was intense and thorough. The process was first a phone screen with HR, three one-to-one video interviews of various technicality with data scientists and direct manager, then finally three on-site interviews with a producer and two senior management. The arrangements for the interview times and dates were very accommodating from HR, which really helped make the process less stressful.

    From what I remember the interviews themselves felt quite informal and the interviewers were all very friendly and not at all intimidating. The balance of questions ranged from tell me about yourself (each one to start), to what kind of games do you play, to graphs being shown and being asked to interpret what they might mean. Even though I remember being under pressure at times when I couldn't think of answers straight away, I was never made to feel stupid at any point.

    Overall the interview process was long and intense, but HR was very informative at each step and it was made very clear the reasoning behind it (technical ability and cultural fit).

    The video interview was with team leader, and he asked about previous experience, but going into more technical details, skills and, of course, my motivation.

    After submitting my CV, I was emailed to invite me to a recorded interview with basic competency questions. Then I moved to the technical test which was about some basic statistics and programming. After that, I interviewed with two teams; each one with a business performance manager and two data scientists. I did not make it to the final round with the Head.

    HR mailed me that they shortlisted the application. Sent me an aptitude test. Pretty easy. Had a tech interview next. Rejected saying they thought I fitted in with the company's cultural values but found someone else more closely tied to the gaming industry

    I had 4 rounds of interviews. I did not get any further. The first two rounds were soft-skill oriented and tested my business awareness. The next two rounds were focused on specific questions, mainly around SQL and AB testing. I failed in this round. I am not good at writing SQL from memory. Assuming the interview is representative of the actual responsibilities , the role is more of a product data analysit than data scientist. There were very few questions around ML/Python. The process was efficient, King was really flexible and the HR staff were quick to reply and even gave me specific feedback. My overall experience was therefore very positive.

    1. Phone screen with HR
    2. Meeting with tech lead
    3. Meeting with a senior data scientist
    4. Meeting with line managers/product owners

    Ich habe mich online beworben. Der Vorgang dauerte mehr als 4 Monate. Vorstellungsgespräch absolviert im Januar 2018 bei King.

    Vorstellungsgespräch

    I was contacted on January 2018 for a data science position where I have to do an exam that assess logical thinking, data modelling, business perspective and programming skills. The exam lasted two hours which was not hard. I didn't hear from them in more than a month, they alleged they lost track of my application. Because I did a good job at the exam I was able to pass to the next phase however they were setting me in a position in Stockholm but I previously applied for a position in San Francisco. I mentioned them I applied to San Francisco and so we agreed they will check with their peers in SF to check for availability if not we would proceed with the position in Stockholm. After almost two, they contacted me with the SF team. We scheduled a Skype interview for Friday that week, the HR guy never showed up. Already sent an email complaining.
