Business Development Internship Interview

Anonymous Interview Candidate

I applied through college or university and interviewed at Criteo.

Interview Details – Applied for an internship position and heard back the next day. Set up a phone screening interview a few days later. Then I was asked to come in for an in-person interview. I interviewed with a supervisor and director and was asked basic interview questions. I then was given a tour of the office space and it was a pleasant atmosphere.

Interview Question – Basic interview questions.   Answer Question

Sales Director Interview

Anonymous Interview Candidate

I applied online and the process took 3 weeks - interviewed at Criteo.

Interview Details – Saw the job posting on VentureLoop so applied through the company's website. Got contacted by an HR Recruiter a few weeks later.

After a phone screen the HR recruiter said there would be an online test. If I passed the test, I would interview with the hiring manager. She said after the test, she would immediately know how I performed--she didn't. She waited two weeks to let me know I they weren't proceeding forward with the interview process. She never told me how I did. As a result, I feel like this discourtesy deserves divulging the test question to all you.

The online test has 8 questions and must be completed within 20 minutes. The last question, though, has four parts. Apparently they get progessively harder. And now, for your unfair advantage:

Question 1
An ad campaign has generated 1 million ad impressions and 6000 clicks.
What is the CTR (ClickThrough Rate)? (in percentage)

Question 2
An ad campaign has generated 5000 clicks and 100 transactions.
What is the conversion rate (in percentage)?

Question 3
With a budget of $5000 and a CPC (Cost per click) = $0.4, how many clicks an advertiser can buy (integer without unit)?

Question 4
An ad campaign has a CTR = 0.6% and a CPC = $0.4.
What is the equivalent CPM (in dollar)?

Question 5
An ad campaign has a CPC = $0.5, a conversion rate = 3% and an average transaction value of $260.
What is the Cost of Sales of the campaign (cost of the ad campaign divided by the revenues generated, in percentage)?

Question 6
With a margin on revenues of 13%, an average transaction value of $290 and a conversion rate = 0.7%, what is the maximum CPC an advertiser can afford without losing money (in dollar)?

Question 7
During his browsing, a user is randomly exposed to two ad banners A & B. Those two banners are equally likely to be shown. One and only one banner is shown per page.
After two pages of browsing, what’s the probability that the user was shown only banners A (in percentage)?

Question 8
A/B Testing campaign: Measuring the impact of Criteo retargeting ads compared to a control group
Number of Unique users Number of transactions on client site
Group A exposed to Criteo banners 600,000
Group B Control group not exposed 50,000

a. Is it a problem to have a control group smaller than the Criteo group? Yes / No
b. What incremental revenues per user Criteo has generated for the client advertiser (in dollar, rounded to the cent)?
c. What total incremental revenues Criteo has generated for the client advertiser?
d. With $200.000 revenues following clicks on banners for group A (post click), what is the related post view (view through) effect in revenues generated by Criteo campaign?

Very Easy Interview

Technical Solutions Engineer Interview

Anonymous Interview Candidate
Munich (Germany)

I applied through a recruiter and the process took 4 days - interviewed at Criteo in January 2014.

Interview Details – Horrible Process. Stereo-Typical French Attitute and Ignorance. Orthographic and Grammar Mistakes in E-Mail, no Greeting formula or CI, horrible code of conduct towards human beings. My advice would be to steer clear of this company.

Interview Question – All technical question have been exceptionally easy, unambitious and uncreative while stating the opposite in the introduction of the test. Most "difficult" question was to color a CSS background in red - Roflcopter.   View Answer

Reason for Declining – The spelling, grammar and reasonableness of the reply were so horrible that I did decline.

Account Strategist Interview

Anonymous Interview Candidate
London, England (UK)

I applied through an employee referral and the process took 4+ weeks - interviewed at Criteo in November 2013.

Interview Details – I was referred by a friend who was working at Criteo. The first stage was a phone interview with HR who asked general questions about the company and my background, the next stage was a phone interview with the manager which was quite similar to the first stage. Then I was invited to face-to-face interview with the manager and VP. I had to prepare a presentation based on a case study. I was asked very detailed questions about the arguments I made in the presentation. After the presentation I had a face to face interview with the manager asking me about my motivations, experience, etc. The whole process was very professional and handled very well.

Interview Question – There were very detailed questions related to the information you included in the presentation so make sure you prepare well.   Answer Question
