Step 2: Technical Phone Screen
Datadog’s technical phone screen lasts about an hour and is conducted in CoderPad. You will get two questions in this interview. The part below called “Types of Interview Questions to Expect at Datadog” will talk about what we know about how they ask questions.
Depending on the role and level of seniority, onsite interview loops can be a little different, but this is what you’ll usually get.
- Coding (1 hour). This interview will be conducted in CoderPad. Read the Coding section below to learn more about the types of questions you can expect.
- [Only for roles below Staff] Second coding (1 hour). As above.
- System design (1 hour). You can choose which tool to use for this interview; many applicants choose Excalidraw. Read the section below on System Design to learn more about the types of questions you can expect.
- Behavioral (1 hour). A hiring manager or director of engineering will be in charge of this interview. There might be some technical questions on it! See the section below on Behavioral for more information on what kinds of questions to expect.
- [For Staff level roles and above] Presentation (1 hour). This will replace one of the coding rounds. A group will ask you to talk about a project you’ve worked on before. You’ll have to explain the business context or reason for what you did and defend the technical choices you made. You might have to choose which teams you want to interview ahead of time so that people from those teams can show up.
Types of Interview Questions to Expect at Datadog
From the first technical phone screen to the onsite coding rounds, you can expect algorithmic questions. However, they probably won’t be exact copies of questions from LeetCode; Datadog has their own question bank. We’ve heard that the questions are a hybrid between practical and LeetCode-style. They might start with something like what you can find on LeetCode and then add more complexity. Datadog themselves recommend practicing medium-level LeetCode questions. You might be asked questions like these:
- Bucketing numbers given specific requirements
- Find the sum of the sizes of all the files in all subdirectories from a root directory.
- Write a buffered file with an interface and a file class.
Below are the technical topics you’re likely to encounter in Datadog interviews. To compile this list, we did two things. First, we spoke to some current and former Datadog engineers. Then we cross-referenced all the anecdotes we heard with Glassdoor data AND our own data-set of mock interviews:
We’ve heard that this round is less broad than it can be at other companies. You won’t be asked to “Design Twitter”, for example. Instead, you might be asked, “Given a service that returns flight deals for the last seven days, design a system that shows relevant flight data to a user and lets them know when there’s a new flight that fits their needs.” ”.
As one of our users said:
It may be a fair interview, but it’s also used to level up, so make sure you know how systems work. We’ve heard of candidates being down-leveled for less-than-flawless performance here.
This interview will be with someone in a leadership role at the company, possibly a director. It will contain some standard behavioral questions but also some technical questions about your past work.
You might be asked to show a simple design of something you built at a previous company. They will want to know why certain design decisions were made so they can see how you affected the project and how much experience you have working with others.
