I applied through an employee referral. The process took 2+ months. I interviewed at Intel Corporation (Haifa) in Oct 2024
Interview
The technical round included two interesting coding questions, one related to multithreading and synchronization, and the other focusing on string processing.
Overall, with well-structured questions that tested both multithreading concepts and algorithmic thinking. I highly recommend preparing for concurrency and real-time processing challenges if you're interviewing for a similar role.
Interview questions [2]
Question 1
1. Multithreading Synchronization
I was given two functions, func_a() and func_b(), each running in a separate thread:
void printA() {
while(1)
print("a");
}
void printB() {
while(1)
print("b");
}
Each function runs indefinitely, printing either "a" or "b". The task was to introduce synchronization mechanisms (such as mutexes, semaphores, or condition variables) to ensure the output alternates as ABABABAB rather than random sequences like AAA BBB or AAABBAAAAA.
This problem is similar to LeetCode 1115 - Print Foo Bar Alternately, where two threads need to synchronize their execution.
2. First Unique Character in a String
The second question involved processing a string and returning the first character that appears only once. This problem is identical to LeetCode 387 - First Unique Character in a String.
Follow-up:
The interviewer extended the question, asking how to solve it in a streaming scenario, where characters arrive one by one. This variation aligns with LeetCode 1429 - First Unique Number, requiring an efficient way to maintain the first unique character dynamically as new characters arrive.
Asked about background, what I did in university
asked about projects
did asked two interview questions
explained what they do in there daily basis, explained about the company, how many employees in the team, and they asked how can I contribute to them
It started with an hr interview, than I had 3 hours technical interview, which splitted to 1 hour for each interview, each one was a diffrent interviewer, 1 question was about system design, 2nd was leet code sytle question, and last was understanding existing code and implementing change
Interview process was went good they have asked regarding my projects
and skills that I have mentioned in resume it was first interview So I was not able to answer properly but interviewer was good and went well

Question 1
Do you know python? and which languages do you know
