Application or Resume Submission: You begin by submitting your resume and application through Juspay's career portal or by other means such as job boards or LinkedIn.

• Initial Screening: The first step may involve a phone screen with a recruiter or HR representative. They might ask you about your background, experience, and your motivation for applying to Juspay.
• Technical Interview (Phone or Video): After the initial screening, you might have one or more technical interviews. These interviews will likely assess your technical skills related to ReactJS. Expect questions and tasks related to React components, state management, routing, and other front-end development topics. You may be asked to write code or solve real-world problems during these interviews.
• Behavioral Interview: In some cases, you might have a behavioral interview to assess your soft skills, problem-solving abilities, and cultural fit with Juspay's team.
• Code or Project Review: You might be asked to submit a code sample or a small React project you've worked on. The interviewer(s) will review your code to evaluate your coding style, structure, and best practices.
• On-Site or Remote Interview: Depending on the location and the company's preference, you might be invited for an on-site interview or a remote interview via video conference. This may include multiple technical interviews, coding exercises, or system design discussions.
• Technical Challenges: In some cases, you may be given coding challenges or tasks to complete within a set time frame. These can be done remotely or during an on-site interview.
• Final Interview: You might have a final interview with a senior technical leader or manager to discuss your skills, experiences, and how you would contribute to the company's goals.
• Reference Checks: Juspay might contact your references to verify your work history and character.
• Offer and Negotiation: If you successfully pass all interview stages, you will receive an offer. You can negotiate the terms of the offer, such as salary, benefits, and start date.
• Offer Acceptance: Once both you and the company reach an agreement, you'll formally accept the offer and complete any necessary paperwork.
