About Open

**Open — company profile** Open Financial Technologies, which operates as Open (open.money), is a Bengaluru-headquartered fintech company founded in 2017 by Anish Achuthan, Ajeesh Achuthan, Mabel Chacko and Deena Jacob. Open describes itself as Asia's first neobanking platform for SMEs and startups, and has been building business banking products for that segment since 2017. Rather than holding a banking licence itself, Open layers software over partner-bank infrastructure to give small and medium businesses a connected business account experience — combining banking, payments, accounting, expense management, payroll and reconciliation into a single platform aimed at reducing manual finance operations for founders and finance teams. According to the company, Open currently serves more than 3.5 million (35,00,000) SMEs and processes approximately US $35 billion in transactions annually. Open is a Series D company and has raised $186 million in funding from investors including Tiger Global Management, India Infoline and Arvon Investments, at a reported valuation of around $940 million. The company is headquartered in Bengaluru and offers hybrid and remote working options, hiring across India and Singapore. Its careers page states that Open is hiring across engineering, design, product, GTM and operations, spanning 15+ departments and growing, and that it consistently seeks exceptional engineering, design, compliance and enterprise-delivery people. Open publishes and updates its live roles on its Keka careers portal, linked from its careers page, and explicitly welcomes unsolicited applications with the note: 'Don't see your role? Send us your work. We'll find the right fit.' The careers page also lists an email contact channel for candidates who do not find a matching open role. **Industry:** Fintech / Neobanking **Headquarters:** Bengaluru, Karnataka, India **Official website:** https://open.money/ **Why work here as a fresher** Open is the kind of company where early-career talent is given real scope rather than busywork. Interns and freshers are placed on live problems, paired with experienced mentors, and reviewed on the same quality bar as everyone else. That combination — real ownership plus real feedback — is what turns a first role into a genuine career head start. **Culture** Expect a fast-paced, outcome-oriented environment with flat communication, short feedback loops and a strong bias for action. Teams are small enough that your contribution is visible and large enough that you learn from people who have already solved the problem you are facing. Learning, curiosity and honest debate are valued over hierarchy. **Growth & hiring** Open hires internships across engineering, data, product, design, marketing, finance and operations, and a meaningful share of its early-career hires convert to full-time offers. All openings are published on the company's official careers page, and applications for this role are submitted directly to Open there — no middlemen, no aggregators.

Expert Tips

  • Practice LeetCode easy and medium problems before the OA — focus on arrays, strings, trees, and graphs.
  • For system design, use the RESHADED framework: Requirements, Estimation, Storage, High-level design, APIs, Detailed design, Evaluation.
  • Prepare 3–4 STAR stories covering: a challenge you solved, a time you worked in a team, a project you owned end-to-end.
  • After every coding solution, proactively state the time and space complexity — interviewers expect it.
  • Study common CS fundamentals: process vs thread, TCP vs UDP, REST vs GraphQL, SQL indexing, CAP theorem.
