1. How to check a number, whether it is power of 2 or not, in as single statement.
Ans : If the below statement is true then it is the power of 2. if(n!=0 && n & (n-1) == 0).
Or, you can just log that number to base 2. If you get an integer, it’s a power of 2.
If it were a doubly linked list, we could just go through it all the way to the end and then go back ‘n’ steps to get to the node we want. But since we have to do this for singly linked list where no such method will work.
1. Take two pointers to the head node. 2. move first pointer ‘n-1’ steps forward and then start the second pointer. 3. The second pointer will be ‘n-1’ steps back when the first pointer gets to the end, which is what you want. Here is the program.
1. we will traverse the list to the end using recursion and then will return ‘n’ steps :
The volatile keyword is meant to stop the compiler from making any changes to objects that can change in ways that the compiler can’t predict.
Things that are marked as volatile are not optimized because their values can be changed at any time by code that is not part of the current program. When a value from a volatile object is asked for, the system always reads it from memory instead of keeping its value in a temporary register. This is true even if the same object’s value was asked for before. So the simple question is how can a variable’s value change in a way that the compiler can’t guess?
5. What is mutex and semaphore, what is difference in both, is binary semaphore and mutex are same.
Ans : As per operating system terminology, the mutex and semaphore are kernel resources that provide synchronization services
1. Mutex, which stands for “mutual exclusion,” keeps multiple threads from changing the same important part of code at the same time. You lock a mutex before entering a sensitive section of code and then unlock it when you’re done to control who can see it.
2. Semaphore: This is used to keep two threads running at the same time and to protect important parts of the code.
Both can be used in the same situation, but sometimes you need to use a specific one. For example, to protect the for part of shared memory, you will only need to use a mutex.
Read page number 536 from beginning linux programming for complete understanding of the topic.
Ans: Each process has one linear virtual address space, with addresses running from zero to some huge maximum. It need not be contiguous; i. e. , not all of these addresses actually can be used to store data. Virtual memory is divided into pages of 4KB each. Virtual memory is an operating system feature that lets a computer make up for the lack of physical memory by moving pages of data from RAM to a secondary disk for a short time.
This is because we often need to load a big program, like a movie or game. But your computer might not have enough free RAM space every time. To fix this, the operating system will have to move some pages to the hard drive so it has room to bring back the pages it needs right away from temporary disk storage. This process is called “paging” or “swapping,” and the hard drive space used for this is called a “pagefile” or “swap file.”
With over 15,000 employees globally, Broadcom is a leading designer and developer of semiconductor and infrastructure software solutions. Landing a software engineering role at this tech giant can be a major career milestone. However, Broadcom’s rigorous interview process is known to challenge even the most seasoned candidates.
This insider guide shares tips, sample questions, and advice for mastering your upcoming Broadcom interview Use these resources to highlight your skills and stand out from the competition.
Broadcom’s Software Engineering Interview Format
For software engineering roles Broadcom’s interview process typically comprises
- Initial phone/video screening with recruiter
- Technical phone interview
- On-site interview (4-5 rounds)
- Manager video call
The on-site rounds involve both technical and behavioral questions and may include written coding challenges. Interviewers will assess your grasp of computer science fundamentals, programming abilities, communication skills, and problem-solving approach.
Expect questions tailored to the specific role you are applying for, such as front-end back-end full-stack, cloud, etc.
How to Prepare for Broadcom’s Software Engineering Interview
Follow these tips to get interview-ready:
-
Review your resume – Refresh your memory on all the projects and technologies you’ve worked on.
-
Study computer science basics – Brush up on fundamentals like data structures, algorithms, design patterns and object-oriented concepts. Know Big O notation complexity analysis.
-
Practice coding – Solve problems on platforms like LeetCode across languages like C++, Java, and Python. Master language syntax, data structures, and algorithms.
-
Understand Broadcom’s technologies – Research the specific products, services and technologies used at Broadcom that relate to the role you are applying for.
-
Prepare STAR interview stories – Craft compelling stories highlighting your skills using the STAR method (Situation, Task, Action, Result). Quantify achievements.
-
Conduct mock interviews – Enlist a friend’s help or use services like Pramp to practice answering common software engineering interview questions.
-
Rest up – Get a good night’s sleep before your interview to be alert and focused.
Technical Software Engineering Interview Questions
Here are some common technical questions asked by Broadcom:
Q: How would you design a parking lot using object-oriented principles?
A: I would use classes like ParkingLot, Level, ParkingSpot, Ticket, ParkingAttendant, etc. Key responsibilities would include managing parking spot availability, processing ticket payments, assigning parking spots, and calculating fees based on parking duration.
Q: Explain how you would implement a hash table data structure.
A: I would create an array of linked lists and use a hashing function to map key-value pairs to an index in the array. Chaining with linked lists handles collisions. I would analyze the hash function and capacity to minimize collisions and ensure O(1) lookup time.
Q: Given two version numbers as strings, write a function to compare which is higher.
A: I would split each string on ‘.’ to get major/minor/patch version values. Then compare them from left to right – for example 2.3.4 is higher than 2.3.1. I would handle edge cases like missing minor/patch values and handle numeric comparisons.
Q: Design a web crawler that indexes web page contents.
A: I would use a queue to manage URLs to crawl. The crawler would remove each URL from the queue, download contents, extract links, add to index, and add new links back to queue. I would control crawl rate, handle robots.txt, garbage collect old indexes, and store indexed data efficiently.
Q: How can you optimize a React application’s performance?
A: Tactics include keeping component state local where possible, using PureComponents for better memoization, lazy loading components, optimizing images, using production build, avoiding inline function definitions in render, and identifying unnecessary re-renders with React profiler.
Broadcom Behavioral Interview Questions
Behavioral questions assess your soft skills and past experiences:
- Describe a time you overcame a difficult technical challenge.
- Tell me about a conflict you faced working on a team and how you dealt with it.
- When have you had tight deadlines and how did you manage them?
- What would you do if you discovered an error in code that was already released?
- How do you stay up-to-date on the latest technologies and industry trends?
Use the STAR method to emphasize how you drove positive outcomes.
