I interviewed at Blizzard Entertainment (Irvine, CA) in Aug 2020

Interview

The best interview I've ever had. Everyone is a joy to talk to and truly wants to get to know you. The teams are made of clever and kind people who are very passionate about the products they work on and the teams they collaborate with.

Interview

Initial application and brief phone interview with a recruiter followed up by a second interview with the team that you would be working under. Second interview was slightly strange, and mic quality on the interviewer's end was very poor and made understanding some questions difficult. Aside from that, the interview was fairly standard.

Interview Questions
  • Asked to tackle a few hypothetical situations related to what you would be doing. These hypotheticals were a bit strange, however, as you are presented with very little information and it seems like the team wants a specific answer rather than to follow your thought process.

I got asked some background questions on first round. Very chill overall. They were looking for someone with engine experience. After that I waited 3 months to know that I didn't make the second round.

I applied through a recruiter. I interviewed at Blizzard Entertainment in Apr 2021

Interview

Recruiter then a friendly meeting with the manager to learn about the team and discuss experience. Then a take home task that you should "only spend and hour or two" on. As a "conversation starter" for your next interview. I found out that if you don't spend many hours on this there won't be another conversation. 3 of the options require UML, which I was surprised to see.

Interview Questions
  • Software Engineering (pick whatever language you are most comfortable in) a. Utilize Blizzard Hearthstone API (See: Getting started and API guides) to retrieve card data i. For the purposes of this exercise, a proper secret management mechanism is not required. Use of an industry standard solution (Vault, Parameter Store, etc.) can be implied in your documentation. ii. This does not need to be a running service hosted somewhere. We will review your submission and discuss your strategies. b. Create web application to render requested information from the API into a human readable page i. Retrieve details of any 10 cards with the following criteria 1. Class: Druid OR Warlock 2. Mana: At least 7 3. Rarity: Legendary ii. Display results sorted by card ID in a human readable table that includes: · Card image · Name · Type · Rarity · Set · Class a. Provide link to repository for application source and documentation 2. Reliability Engineering a. Examine UML sequence diagram of a proposed new service b. Describe the following i. What is the critical user path? ii. Propose graceful degradation of individual components iii. Propose any relevant SLAs, SLIs, and SLOs for the application 1. Describe how/where/what you would measure and propose initial SLO/SLA values and their justification for a business critical service. 2. Describe what metric types or events you use in your SLIs and include any filtering criteria. a. The service is now live but your monitoring of one of the critical software components indicates the error budget burn rate is excessive. You approach the development team and determine they have an aggressive deployment cadence and a number of pushes have had issues. What do you suggest and discuss with your partner team?

Systems Internals a. Scenario: Your partner development team comes to you to help them with some performance related issues. They say, according to their calculations and local testing, they should be able to be able to achieve a much higher request rate before they reach their thread limits. However, in their staging environment, they notice the average request takes significantly longer than it should to process so the number of in-flight requests quickly climbs and exhausts system resources. The developer says, when they test locally, the service responds consistently with single-digit latency. b. Utilize the following data sources to determine why this is happening and make any necessary recommendations. i.

Very unprofessional - Recruiter scheduled time and NEVER called. After I sending a follow up email, I was completely ghosted. Blizzard needs to get it together and stop wasting people's time.

Interview

From the first call with Jenna to my final call with Christy, I was impressed by the kindness and understanding of everyone involved. The interviews were thorough yet fun. They were to the point but didn't feel rushed. Most of all the team really cared about the questions I had as much as their own, especially Christy who asked what I needed from a manager. That sealed the deal for me. I had interviewed at many great companies but Blizzard was miles above the others.

Interview Questions
  • What is the difference between the role of a Product Management and Product Designer? Describe your leadership style. What is your approach for when things are not going well?

Process was long and grueling. From application submission to final decision took about six months. Even though it was slow, the people were cool and my HR rep was great. After the resume submission, there was a phone interview with my HR rep, then a design test, then a panel interview with three people. This was followed by a gauntlet of four more panel interviews, each with three people.
