2.1 Stage 1: Application & Resume Review

The initial stage at KANERAI focuses on a thorough screening of your resume and application materials. The team looks for evidence of strong software engineering fundamentals, experience or curiosity in distributed systems, cloud computing, and data management, as well as a demonstrated passion for learning and problem-solving across the technology stack. Candidates with a background in advanced analytics, data visualization, or financial technology are particularly valued. To prepare, ensure your resume highlights relevant projects—especially those involving large-scale data, real-time systems, or cross-functional technical work.

2.2 Stage 2: Recruiter Screen

This stage typically involves a 30-minute phone or video conversation with a recruiter or HR representative. The discussion centers on your motivation for joining KANERAI, your understanding of the company’s mission, and your general fit for a high-performing, entrepreneurial team. Expect to discuss your work preferences (remote, hybrid, or onsite), your technical interests, and your career trajectory. Preparation should include researching KANERAI’s products and culture, and articulating why you are drawn to complex, impactful software engineering challenges in the financial domain.

2.3 Stage 3: Technical/Case/Skills Round

KANERAI’s technical rounds are rigorous and multi-faceted, often conducted by senior engineers or engineering managers. You may encounter a combination of live coding exercises, algorithm design, and system design questions. Topics often include implementing data structures (e.g., LRU cache), graph algorithms (e.g., shortest path), recursive and iterative coding (e.g., Fibonacci sequence), and designing scalable systems (e.g., real-time transaction streaming, data pipelines). You may also be asked to demonstrate your approach to cleaning and organizing data, architecting ETL pipelines, or discussing tradeoffs in distributed and cloud-based systems. Preparation should focus on practicing code implementation, system design, and articulating your reasoning clearly.

2.4 Stage 4: Behavioral Interview

In this stage, expect to meet with engineering leaders or potential teammates. The focus is on evaluating your collaboration style, communication skills, and alignment with KANERAI’s values of resourcefulness and teamwork.
