Big Data Engineer, New Hampshire Interview Experience - Merrimack, New Hampshire
Process
First, there was an HR call that focused on my resume. Then, the HR set me a technical phone interview in two days. After that, I got a call from a Sr. Software Engineer who asked me basic core Java questions, such as:
- Singleton class and how to ensure it has only one instance
- Difference between a static block and a static method
- How to get duplicate values from a database (clue: using the HAVING clause)
- Difference between observer and observable classes
- What are synchronization and serialization?
- Final, finally, and finalize
- How to print all the rows in a database
Apart from these, be prepared with Hadoop and MapReduce questions.
Now, I am waiting for the result. If selected, I will be called for an onsite interview.
