Commonly Asked Interview Questions for Software Development Engineer at Nokia
Technical Questions (Coding and Data Structures)
- What are the key differences between C and C++?
- Tests understanding of programming languages used at Nokia. Explain C as a procedural language and C++ as supporting both procedural and object-oriented programming, mentioning features like classes, inheritance, and polymorphism.
- Can you explain the concept of pointers in C/C++?
- A fundamental question for roles involving C/C++. Describe pointers as variables storing memory addresses, their use in dynamic memory allocation, and examples like linked lists or trees.
- Solve a coding problem involving a single linked list (e.g., reverse a linked list, find the middle element, or detect a cycle).
- Nokia frequently asks linked list problems. Be prepared to write code for operations like insertion, deletion, or traversal, considering edge cases like empty lists.
- Implement a substring matching algorithm (e.g., using Knuth-Morris-Pratt or Boyer-Moore).
- Tests string manipulation skills, common in Nokia interviews. Explain the algorithm’s logic and code it efficiently, discussing time complexity.
- Write code to solve a problem using data structures like arrays, trees, or graphs (e.g., swap numbers in an array, palindrome check, or binary tree traversal).
- Expect problems of easy to moderate difficulty (e.g., LeetCode medium-level). Practice problems on platforms like LeetCode or HackerRank.
Technical Questions (System Design and Networking)
- Design a notification system. Would you use a pull-based or push-based approach?
- Tests system design skills, relevant for Nokia’s telecom focus. Discuss trade-offs: pull systems for less frequent updates, push for real-time needs.
- Explain networking protocols like IP/TCP/UDP.
- Nokia’s SDE roles often involve networking knowledge for 5G technologies. Describe each protocol’s role, layers in the OSI model, and their use in telecom.
- What are the basics of object-oriented programming (OOP)?
- Expect questions on concepts like inheritance, polymorphism, encapsulation, or virtual functions. Be ready to implement or explain them with code.
- How would you debug a performance issue in a software application?
- Tests debugging skills, critical for Nokia’s Linux-based development. Describe steps like checking logs, profiling, and identifying bottlenecks.
- Explain the concept of multithreading and its challenges.
- Relevant for embedded systems or concurrent programming at Nokia. Discuss thread synchronization, deadlocks, and race conditions with examples.
