Hire deeply vetted Kafka developers

Kafka is a stream-processing platform that ingests huge real-time data feeds and publishes them to subscribers in a distributed, flexible, fault-tolerant, and secure manner. Kafka can be easily deployed on infrastructures starting from bare metal to docker containers. A core ability of Kafka is the management of huge volumes of data while staying responsive; this makes Kafka a preferred platform for fast-scaling enterprises, especially with an enormous amount of data.

Hiring a fresh talent in Kafka requires testing and reviewing candidates for their technical skills and proficiency. This means a fair amount of technical abilities or experience is required. However, if you're coming from a non-tech background and looking to hire a Kafka developer, we have an excellent resource for you. Here, we will help you understand what it takes to hire dedicated Kafka programmers to build secure and stable software.

At a high level, Kafka developers should have the following skills in their arsenal:

Data management is the process of ingesting, storing, organizing, and maintaining the data created and collected by an organization. Effective data management is a crucial skill for Kafka developers to deploy IT systems that run business applications and provide analytical information. It helps drive operational decision-making and strategic planning by corporate executives, business managers, and other end users. It is best to hire Kafka developers who are professionally sound in this aspect.

Some of the most popular websites, such as Google, LinkedIn, eBay, and Amazon, are written extensively using Java and its frameworks. Frameworks are tools with pre-written code, which act as a template or skeleton, and are reused to create an application or website.

So while hiring Kafka developers, ensure they are conversant with the Java programming language and its frameworks.

Today, vast amounts of data are being generated by multiple devices, live streams, and systems every second, and more devices are connecting to the internet daily. The first need in Big Data applications is to solicit data from multiple sources and store them in a central repository. Kafka acts as an intelligent middle layer and decouples diverse, real-time data pipelines. It can collect data from publisher sources like web and mobile applications, databases, logs, flume, streams, message-oriented middleware, etc. Thus, you must hire Kafka developers who are familiar with Big data technologies to perform complex data analysis.

The architecture of a system describes its major components, their relationships (structures), and how they interact with each other. Software architecture and design include several contributory factors such as the business strategy, quality attributes, human dynamics, design, and IT environment. Kafka developers need to have high-level proficiency and understanding of the application’s architectural components and design capabilities.

Databases are the most common platform used to hold corporate data. They contain a collection of data organized to be accessible, updated, and managed. The primary technology used to deploy and administer databases is a database management system (DBMS). Knowledge of databases can be considered an essential skill for Kafka developers. You don’t want to hire a developer who is just familiar or has very little knowledge of database systems. Instead, hire a Kafka developer who has extensive knowledge of various DBMS technologies such as MongoDB, Oracle, Cassandra, MySQL, PostgreSQL, etc.

Developers must have solid problem-solving abilities and a creative mindset while working in any technical field or domain. The implementation of different programming techniques for efficient solutions requires both of these qualities in top professionals. Kafka developers need to analyze evidence, question assumptions, test hypotheses, and observe and draw conclusions from any form of data. Creativity and critical thinking is not just a skill but a habit formed to help with problem-solving.

While hiring a Kafka developer, it is crucial to remember that the engineer must have knowledge and proficiency in various programming languages and frameworks and not just be confined to Kafka. Gaining knowledge of data structures and algorithms, along with other technical abilities, is always an added advantage. Hence, when hiring Kafka developers, keep in mind to look for developers with knowledge of technologies such as Java, C++, Python, Ruby, Scala, Spark, etc.

Creating a hiring funnel will provide you with numerous benefits, like assisting you in identifying the top skills and identifying a Kafka developer who will fit into your company's culture.

Whether you're an IT recruiter or a project manager, you know that finding top developers is critical to the success of your project. Here are some sample interview questions to use when looking for a new Kafka developer to work on your online applications.

Here are some more Kafka developer interview questions that you can ask to assess a developer’s caliber.

• List the various components in Kafka.
• What roles do Replicas and the ISR play?
• What is the process for starting a Kafka server?
• How do you define a Partitioning Key?
• What is the main difference between Kafka and Flume?
• How to balance loads in Kafka when one server fails?
• Explain the role of the Kafka Producer API.
