I applied through a recruiter. The process took 2 weeks. I interviewed at Braze in Mar 2021
Interview
1hr Technical Assessment, then half-day of interviews consisting of debugging/refactoring code exercise (1hr), system design (1hr), behavioral (1hr), HR interview (15 min)
My experience varied by who I spoke with. Really enjoyed the technical assessment and my conversation with the developer administering it. Also enjoyed the interview with the hiring manager.
Felt the debugging interview was poorly designed. They ask you to download a zip with a program that implements the caesar cipher and debug some failing unit tests. But it didn't work, and I had to change from taking the test in python to taking the test in c#. The code is absolutely terrible and cryptic, and for the debug portion you aren't really allowed to refactor the code. They just want you to find the specific thing wrong with that one test. After 30 min, they begin the second part of that assessment and they let you start refactoring the code.
The system design interview question was fairly standard, though I feel the prompt wasn't clearly explained by my interviewer.
My worst interactions were actually with the in-house recruiters. Very unprofessional, and I was actually ghosted during my scheduled 15 min HR interview. Got a rejection email very late Friday (like 11:30 pm) night from him 3-4 days later.
Interview questions [1]
Question 1
System Design Question was about designing a web scraper that would gather data about advertisements listed in a search engine for a given keyword. The idea was that a marketing department would supply a list of keywords and after your process would run, they would analyze the data to see if their ad's or their competitors ad's were showing up more
I applied online. I interviewed at Braze (São Paulo, São Paulo) in Jan 2026
Interview
Check the comments about toxic culture and the interview process, because this company really fits that description. The interviewers have terrible people skills and ask puzzle-style questions for a senior role.
I passed the first algorithm interview and was then scheduled for four more. The debugging interview was a complete joke and again focused on puzzle-style questions instead of real-world problems.
The interviewers don’t help when you ask questions. They are only there to judge you and make the process harder. The culture seems like they are only looking for yes-men.
Interview questions [4]
Question 1
The "debugging" interview was a Caesar cipher puzzle. Each character was shifted by some +/− offset, but the code was badly written: heavy ASCII character mapping, non-descriptive variable names, and messy logic. It felt like a trick puzzle, not real debugging work you’d do in a senior role.
The first algorithm interview was about removing fields or detecting changes in object fields. There were three questions that could basically be solved by tweaking the first solution, but they wanted me to reimplement it each time instead of reusing or adjusting what I had already written. Basically, we were counting how many changes exist between two objects recursively.
System design interview for google search, you have a list of 1 million keywords and you have to create a web scraper to search each keyword on google every day.

Interview
Default interview process + debugging round: HR Interview, Coding interview, System design, Debugging interview.
Focusing on the debugging round is essential -> They expect you to be able to identify patterns and fix them on failing tests
I applied online. The process took 3 weeks. I interviewed at Braze (Milpitas, CA) in Sept 2025
Interview
Applied to Braze via Indeed. The recruiter reached out by email to schedule an initial phone call, and their scheduling system made providing availability simple and intuitive. We spoke for about 20–30 minutes; the recruiter was friendly, helpful, and clearly explained the process, emphasizing the importance of preparing for the technical screen.
The technical screen itself went smoothly, and scheduling the virtual on-site interviews was equally seamless.
Although I didn’t prepare as thoroughly as I should have and one of the intensive sessions exposed some major deficiencies on my part, both interviewers were friendly, flexible, and encouraging throughout.
Overall, it was a very positive experience. I appreciated having the chance to meet with real developers rather than relying on online assessments or timed GitHub challenges.
