Infineon Technologies visited Lovely Professional University in April 2023 for interns. I have applied for the software role. The selection process was around 3 days long and consisted of 1 Online round + 4 rounds of technical interviews + 1 HR round
Before the start of the whole assessment, there was an initial CV shortlisting round after which around 500 candidates were allowed to go for the further rounds.
Round 1 (Online Assessment) – Day 1 was all about the online test which was conducted on the GeeekAssess Platform. There were 100 – 110 questions and the time which was given was 120 minutes. The questions were spread in different domains of the fundamentals of computer science. They are OOPS, C, C++, Java, Digital Electronics, Web Development, Machine Learning, Operation Systems, DBMS, and Computer Networks.
Also, each section has there own time limit. The questions were on the medium-hard side.
Advice: Go with GATE-level questions and practice coding-output questions. Also, there is no negative marking in this assignment, so try to answer all the questions.
Around 1/3rd the students got a call for the interview process. All the further interviews were held onme the Webex platform.
Round 2 (Technical Interview 1) – Day 2 – It started with a brief introduction followed by some technical questions. Some of the questions were –
- What is dynamic memory allocation? Difference between malloc and calloc .

After that, they jumped on to the resume discussion and asked me about my projects. Some of the questions were :
- What problem is your project solving for the real world?

After that they jumped on to computer Networks and asked about the OSI model and how a browser work behind the scenes.
Round 4 (Technical Interview 3) – Day 2 – It was a puzzle round and asked 4 puzzles . They were tricky and interviewer were explained multiple times to avoid any kind of confusion. The questions were similar of the following

Some takeways of this experience are :
- Understand the question well before answering to it.
- If you are stuck at some point while answering , don’t hesitate to ask for help.
- Always try to explain your thought process during you are figuring out the answer. Don’t sit still and silent.
- Focus on core fundamental subjects of CS as well
- Most importantly keep a smile on your face while answering . Just chill !! 🙂
All the best ! Hope this experience helped you . Byee
