I applied online. I interviewed at Luxoft in May 2026
Difficult interview
Application
I applied through a recruiter. The process took 2 weeks. I interviewed at Luxoft in Sept 2022
Interview
The first step was an HR interview after that there is an offline code challenge and after that a technical interview. after the technical interview if you passed there is an HR session for salary negotiation and etc. you have about one week for an offline code challenge. Technical interview was a bit difficult not just for the questions, but the interviewer was in hurry and he was asking questions fast!! anyway that was a good experience
Interview questions [1]
Question 1
The offline code challenge was about finding vowels in the array of strings by java 8 . Finding duplicated elements in the array. HashMap typical questions. the time complexity for some sorting algorithms such as mergeSort and quickSort. the difference between HashTable and ConcurentMap. @Conditional and @Profile annotations. the difference between Decorator and Adapter design patterns. SOLID. ACID. some java 8 features and methods such as functional interface and the difference between map() and flatMap(). memory leak topic in java. These are what I remember :)
An easy coding exercise at the beginning followed by a bunch of mostly theoretical questions from the programming language, frameworks, databases, concepts like microservices.
Unfortunately the interviewer was from another project and couldn't answer my questions about the role.
