What interview techniques should you use to hire the best Scala developer?
In interviews, it’s crucial to remember that it’s not about having many questions to ask. To be able to assess a candidate’s skills properly, you have to be prepared with the right questions.
Start the interview by asking the usual generic questions to get an idea of their personality, previous work experiences, as well as their work ethics. It’s also important to note that making the interviewee feel at ease and comfortable will help you get better and more accurate answers.
After the basic questions have been asked, it’s time to ask technical questions to test your interviewee’s knowledge on Scala development. There are plenty of technical questions you can ask, and here are some you can start with:
Q: What are the isInstanceOf and asInstanceOf methods used for in Scala? Is there a similar concept in Java?
A: Both isInstanceOf and asInstanceOf methods are defined in Any class, but the difference lies in this:
isInstanceOf method is used in testing whether the object is of a given type or not. If it is a given type, it returns “true”; otherwise, it returns “false”. See example:
scala> val str = "Hello"
scala>str.isInstanceOf[String]
res0: Boolean = false
On the other hand, asInstanceOf method is used to cast the object to a certain type. See example:
scala> val str = "Hello".asInstanceOf[String]
str: String = Hello
There is a similar concept in Java for Scala’s ‘isInstanceOf’ method: ‘instanceof’. On the other hand, for Scala’s ‘asInstanceOf’ method, there is also a similar concept as seen in this manual type casting:
AccountService service = (AccountService)
context.getBean("accountService");
Q: What is the keyword “object” used for in Scala?
The “object” keyword can be used for different things. Here are three of them:
- To automatically create a singleton object:
object MySingletonObject
- To automatically make an executable Scala program
object MyScalaExecutableProgram{
def main(args: Array[String]){
println("Hello World")
}
}
- To define static members as static variables and static methods without using the ‘static’ keyword. See example:
object MyScalaStaticMembers{
val PI: Double = 3.1414
def add(a: Int, b: Int) = a + b
}
In this example, PI variable and add methods become static members and there’s no need to create a separate object like MyScalaStaticMembers.add(10,20) to call them.
Q: What is the diamond problem and how does Scala resolve this?
A: The diamond problem is also known as the multiple inheritance problem. This happens when there is an inability to decide on which method implementation to choose. For example, we have classes B and C which both inherit from class A, while we have class D which inherits from both class B and C. While implementing multiple inheritance and B and C overrides some methods from class A, there will be a problem and confusion with what D should inherit.
This multiple inheritance problem is resolved by Scala with the concept of Traits and class linearisation rules.
How can Cloud Employee help you?
Here at Cloud Employee, we help companies, tech startups, and SMEs hire the Scala developer they need from the Philippines’ ever-increasing pool of expert IT professionals. We’re a UK-managed IT outsourcing company committed to helping you hire offshore Scala developers through our simple, no-risk and client-oriented business process.
To get started, simply let us know the skills and experience you need. Our team of expert recruiters conducts a local search for available Scala developers who meet your qualifications. Afterwards, we get back to you with a list of pre-screened CVs from which you select the developers you want to interview and do technical testings. We make sure you hire offshore Scala developers you need at zero recruitment fees.
After onboarding, your outsourced Scala developer now works exclusively for you. They work on the same working hours as you do, reporting directly to you from our modern offices.
Meanwhile, Cloud Employee handles everything else so you can focus on growing your business and managing your team. We take care of all HR and general administrative functions, and we also provide your outsourced Scala developer with high-spec hardware and software, fast internet connection, a designated workspace, and full IT support. We make sure they have everything they need to get your job done.
Hire offshore Scala developers to solve your IT hiring needs efficiently. Our Scala developers have a wide range of skill sets which include Java, JVM, Spring, Hibernate, Apache Struts, Java SE, Java EE, and Scala IDE.
What is the dedicated developer model?
Here at Cloud Employee, we employ the dedicated developer model in which we provide our clients with dedicated developers as well as equipment and resources tailored specifically to their project’s requirements.
When you gain a dedicated developer to your team, you gain an outsourced Scala developer who works 100% exclusively for you. They follow only the systems and processes you have, and they use only the tools you use. Moreover, they mirror your working hours, allowing them to work smoothly with you and be seamlessly integrated into your in-house team.
Along with this benefit of reduced risks in miscommunication and miscoordination, another convenience this model brings is that you only pay a single sum of money which already includes the offshore team member’s monthly salary as well as the outsourcing provider’s service fee.
The dedicated developer model is widely preferred by startups and companies due to the hiring flexibility that it offers. With this model, our clients can request the tech talents, equipment, and other services they need for their project anytime, helping them scale their offshore Scala development team as their business grows.
Advantages
- Highly recommended for long-term projects, especially those with a changing scope and undefined specifications
- Works well for short-term projects with a definite scope
- You have full knowledge and control from recruitment to candidate selection, and to the management of the offshore team
- You have full control on quality control and assessment
- You gain an offshore Scala developer or development team who will work exclusively for you; compared to freelance workers, your dedicated Scala developers are more focused on your objectives, goals, standards, and expectations
Compared to other outsourcing setups, Cloud Employee’s dedicated developer model has made task coordination and information relay in offshore development projects faster and more efficient. Ultimately, this business model has also simplified the hiring process and made the outsourcing experience a hassle-free and zero-risk experience all in all.
