As a Software Engineer at League inc., you will design, develop, and maintain scalable software solutions that support the company’s digital health platform. You will collaborate with cross-functional teams—including product managers, designers, and QA engineers—to deliver high-quality features and enhancements that improve user experience for clients and members. Core tasks include writing clean, efficient code, conducting code reviews, troubleshooting technical issues, and participating in agile development cycles. This role directly contributes to League’s mission of transforming healthcare by enabling seamless, personalized digital health experiences.

2.1 Stage 1: Application & Resume Review

The process typically begins with an online application and resume review, where your technical background, software engineering experience, and relevant project work are closely evaluated. This step is conducted by the internal recruiting team, who look for strong evidence of hands-on programming, system design, and familiarity with modern development practices. To prepare, ensure your resume is tailored to highlight experience in building scalable systems, collaborating with cross-functional teams, and any exposure to technologies mentioned in the job description.

2.2 Stage 2: Recruiter Screen

Next, candidates are invited to a short phone screen with a recruiter or hiring manager, usually lasting about 30 minutes. This conversation focuses on your motivation for applying, your technical background, and your fit with League inc.’s values and team culture. Expect questions about your previous roles, programming languages you are comfortable with, and your approach to teamwork and diversity. Preparation should include a succinct personal elevator pitch, as well as clear examples of how your experience aligns with the company’s mission and values.

2.3 Stage 3: Technical/Case/Skills Round

League inc. places strong emphasis on practical technical skills, so this stage typically involves a take-home coding assignment or case study. You may be asked to build a small application, design a system (e.g., a file upload service or digital classroom), or solve a programming challenge in a specific language (often Go, but flexibility is shown for other languages). Assignments are expected to be completed within a 2-3 day window, requiring 4-6 hours of focused work. You should be prepared to write robust, well-tested code and to document your design decisions and trade-offs. Strong preparation involves reviewing core algorithms, system design principles, and best practices for writing maintainable code.

2.4 Stage 4: Behavioral Interview

After successfully completing the technical assignment, you’ll participate in one or more behavioral interviews, often with multiple team members. These interviews explore your collaboration style, communication skills, and ability to navigate challenges in a fast-paced environment. Expect questions about past projects, handling ambiguity, working with diverse teams, and resolving conflicts. To prepare, reflect on your experiences where you demonstrated adaptability, leadership, and clear communication—especially in the context of software engineering projects.

2.5 Stage 5: Final/Onsite Round

The final stage typically consists of two back-to-back interviews, each lasting about an hour, and may be scheduled on the same day. One interview is often technical or architecture-focused, where you’ll discuss your take-home assignment, walk through a system design (such as designing a file upload or digital classroom system), or diagram a service with given requirements. The other interview may focus more on soft skills, problem-solving, and your approach to technical challenges. The interview panel usually includes senior engineers, engineering managers, and occasionally cross-functional partners. Preparation should include practicing whiteboarding solutions, articulating your reasoning, and being ready to present and defend your design choices.

2.6 Stage 6: Offer & Negotiation

If you successfully pass all interview rounds, the recruiter will reach out with an offer and initiate discussions around compensation, benefits, and start date. This stage is handled by the recruiting team and may involve negotiation on both sides. Preparation involves researching industry benchmarks and clarifying your own expectations.

2.7 Average Timeline

The typical League inc. Software Engineer interview process spans approximately 2-4 weeks from application to offer. Fast-track candidates may move through the process in as little as 10-14 days, while the standard pace allows about a week between each stage to accommodate assignment completion and scheduling interviews. Take-home assignments generally have a 2-3 day deadline, and onsite or final round interviews are usually scheduled within a few days of assignment submission. Some variation can occur based on team availability and candidate schedules.
