Heizen is an AI‑powered software services startup that blends deep engineering expertise with proprietary AI agents to deliver enterprise‑grade solutions. Founded by alumni of Microsoft, JP Morgan, IIT and ISB, the company has quickly positioned itself as a trusted partner for startups and large enterprises seeking to automate complex workflows, build robust products, and accelerate time‑to‑market. The culture at Heizen emphasizes continuous learning, mentorship, and a flat hierarchy that encourages every engineer to contribute ideas, experiment with new technologies, and see the impact of their work in real customer deployments. With a remote‑first policy and a vibrant Hyderabad hub, Heizen offers a collaborative environment where engineers can work from anywhere while still enjoying regular virtual hackathons, knowledge‑sharing sessions, and quarterly off‑site retreats. The Associate Software Engineer role is crafted for fresh graduates and early‑career developers (0‑2 years of experience) who are eager to dive into full‑stack development. As an Associate Engineer, you will work alongside senior engineers, product managers, and designers to build and ship features for both backend services and frontend interfaces. The day‑to‑day responsibilities include writing clean, maintainable code, designing and consuming REST APIs, interacting with SQL/NoSQL databases, and gaining exposure to basic cloud infrastructure. You will also participate in code reviews, unit testing, debugging sessions, and iterative deployments, gaining a holistic view of the software development lifecycle. **Key Responsibilities** 1. Develop and maintain backend services using Python, Java, or JavaScript/TypeScript. 2. Build responsive frontend components and integrate them with backend APIs. 3. Design, implement, and optimize database schemas in SQL or NoSQL stores. 4. Write unit and integration tests to ensure code quality and reliability. 5. Participate in peer code reviews and adopt best‑practice coding standards. 6. Collaborate with product managers to translate requirements into technical specifications. 7. Debug and resolve production issues promptly, maintaining high system uptime. 8. Contribute to documentation, API specifications, and knowledge‑base articles. 9. Explore basic cloud services (e.g., AWS, Azure) for deployment and scaling. 10. Continuously learn new tools and frameworks under mentorship from senior engineers. **Tech Stack**: Python / Java / JavaScript‑TypeScript, OOP, Data Structures & Algorithms, RESTful APIs, Git, SQL (MySQL/PostgreSQL) & NoSQL (MongoDB), basic AWS/Azure services. **Growth Path**: Starting as an Associate Engineer, high performers can progress to Software Engineer, Senior Engineer, and eventually Lead Engineer or Technical Architect within 2‑4 years, with opportunities to specialize in AI‑assisted development, cloud architecture, or product management. **Why Join Heizen?** Heizen offers a competitive fixed salary of ₹6‑8 LPA, performance‑linked bonuses, and ESOPs that align employee success with company growth. The remote‑first model provides flexibility, while the Hyderabad office hosts regular in‑person brainstorming sessions and team‑building events. Employees benefit from a dedicated learning & development budget, mentorship programs, and exposure to cutting‑edge AI tools that accelerate software delivery. If you are passionate about building end‑to‑end solutions, thrive in a fast‑moving startup environment, and want to grow alongside industry veterans, Heizen is an ideal launchpad for your engineering career.

What is the difference between WHERE and HAVING clauses in SQL? Answer ▼
Model Answer: WHERE filters rows before any groupings are applied, while HAVING filters aggregated groups after GROUP BY has executed.
Explain SQL Window functions: ROW_NUMBER(), RANK(), and DENSE_RANK(). Answer ▼
Model Answer: ROW_NUMBER() assigns unique sequential integers. RANK() assigns identical ranks to ties and skips ranks. DENSE_RANK() assigns identical ranks to ties without skipping rank numbers.
How do you handle NULL and missing values during data cleaning in Python/Pandas? Answer ▼
Model Answer: Use .isna().sum() to identify missing values. Impute with mean/median using .fillna() or remove with .dropna(subset=[...]) depending on variance impact.
What is the difference between Star Schema and Snowflake Schema in Data Warehousing? Answer ▼
Model Answer: Star Schema has denormalized dimension tables directly connected to the central Fact table. Snowflake Schema normalizes dimension tables into sub-dimensions to minimize redundancy.
How do you calculate MoM (Month-over-Month) growth in SQL? Answer ▼
Model Answer: Use LAG(revenue, 1) OVER (ORDER BY month) to fetch the previous month's revenue and compute (revenue - prev_revenue) / prev_revenue * 100.
