This guide, hosted by Interview Query, will take you through the interview process and provide insights to help you prepare effectively. Let's dive in!
The first step is to submit a compelling application that reflects your technical skills and interest in joining LatentView Analytics as a Data Engineer. Whether you were contacted by a recruiter or have taken the initiative yourself, carefully review the job description and tailor your CV according to the prerequisites.
Tailoring your CV may include identifying specific keywords that the hiring manager might use to filter resumes and crafting a targeted cover letter. Furthermore, don’t forget to highlight relevant skills and mention your work experiences.
If your CV is shortlisted, you will be contacted by a recruiter or hiring manager from LatentView Analytics. They will verify key details such as your experiences and skill levels. The screening may involve behavioral questions and some preliminary technical assessments.
The recruiter call typically lasts about 30 minutes. In some cases, the hiring manager might also join the call to answer any questions you may have about the role and the company.
Following the initial screening, you'll undergo an aptitude test. This test could be game-based and is designed to evaluate your problem-solving skills and analytical thinking. For some roles, there could also be a coding assessment where you'd need to complete programming tasks within a set time frame.
Candidates who pass the aptitude test will then proceed to the technical assessment stages. Specific topics commonly covered include:
After successfully navigating the initial screening and assessments, you will be invited to participate in multiple rounds of technical interviews. These may include:
First Technical Round: Focuses on SQL (joins and queries), basic Python coding, and questions related to your resume.
Second Technical Round: In-depth SQL coding problems, further discussions on Python and Spark, and theory questions related to Spark serialization, types of Hive tables, and partitioning.
Coding Round: Typically involves problem-solving and coding exercises using different compilers (Python, Java, etc.) and might involve real-time coding or take-home assignments.
The last stage is usually a set of interviews that may involve face-to-face meetings or video calls with multiple interviewers, including team members, hiring managers, and possibly clients. These interviews might assess:
Prepare thoroughly for technical questions on SQL and Python, given the weight these subjects carry in the interview process.
