A Software Engineer at Supernova Technology plays a vital role in building and maintaining the industry’s leading cloud-based securities-backed lending (SBL) platform. The company's technology automates the entire life cycle of a loan, connecting financial advisors, clients, and lenders seamlessly. In this role, you will design, develop, and optimize high-throughput, secure, and resilient backend systems that handle complex financial transactions and sensitive data. The impact of your work is immediate and highly visible. You will be responsible for building the APIs, microservices, and data processing pipelines that power real-time financial decision-making. Working on this platform requires a deep commitment to code quality, system performance, and security, as the software directly manages billions of dollars in financial assets. At Supernova Technology, software engineering is a highly collaborative and cross-functional effort. You will work closely with product managers, database administrators, and international development teams to translate sophisticated financial requirements into robust software solutions. This is an exciting opportunity for engineers who enjoy solving complex algorithmic challenges and building enterprise-grade financial technology at scale.

Master the database basics
Given the financial nature of the platform, database performance and data integrity are paramount. Spend extra time reviewing SQL joins, indexing, and transaction management.
Prepare for the unexpected in the OA
Do not assume the online assessment will only cover the languages listed in the job description. Be ready to tackle basic Python or data analysis questions if they arise.
Naming no test cases at all
State what you would test before being asked: empty input, a single element, all elements equal, the maximum permitted size, and the input that exercises the branch you just wrote. It costs thirty seconds and is much of what separates someone who has shipped code from someone who has only solved puzzles.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.
Write a program to reverse a linked list, both iteratively and recursively.

Approach
- Restate the input: its shape, its size, and what is guaranteed about it.
- Name the brute-force solution and its complexity before improving on it.
- Choose the data structure from the access pattern, not from familiarity.
- State the target complexity and say which constraint rules the naive version out.
Follow-up
- How does this change if the input no longer fits in memory?
- What is the worst case, and how likely is it on real data?
Given an array of integers, find the contiguous subarray that has the largest sum.

Read latency spikes on a sixty-second sawtooth
The cached listing read path serves about 14k reads/second at an 85% hit rate. p99 sits at 35 ms for 57 seconds, jumps to 900 ms for 3, and repeats. During each spike the primary shows several hundred identical listing queries starting within the same millisecond, all carrying one large tenant's id. Cache entries use a 60-second TTL. Give the mechanism, the ordered checks, the fix, and the correctness hazard your fix must not introduce.
Approach
- Match the period to a configured number before theorising about load. A spike every 60 seconds against a 60-second TTL is an entry expiring, and you confirm it by correlating spike timestamps with the entry's write time rather than with the traffic curve. If the period had matched a cron or a GC interval instead, this is a different investigation.
- Establish the concurrency of the miss. Several hundred identical queries in one millisecond means the miss path has no coalescing: every request that arrives between expiry and repopulation recomputes. The herd size is that key's arrival rate times its recompute time, so at 1.2k reads/second for the hot key and a 250 ms recompute you expect about 300 concurrent misses, which matches what is observed.
- Add single-flight on the miss path so one caller per key recomputes under a short-lived lock while the rest wait for its result. Prefer stale-while-revalidate where the read tolerates it: return the expired value immediately and refresh asynchronously, which removes the latency spike rather than serialising it into a queue of waiters.
- De-synchronise the keys. Write TTLs with jitter, for example 60 seconds plus or minus 10%, so a deploy or a mass invalidation does not align every key on the same second and turn a per-key herd into a fleet-wide one.
Follow-up
- The same sawtooth appears on a key that is invalidated on write rather than expired. Is that the same bug?
- How does your answer change if the recompute takes 4 seconds instead of 250 ms?

How difficult is the technical assessment?
The online assessment is generally rated as average in difficulty. It contains a mix of multiple-choice questions on general computer science topics and coding challenges that are comparable to LeetCode Easy or Medium problems. Practicing core algorithms and basic SQL queries is the best way to prepare.
