Submitting Your Application

The first step is to submit a compelling application that reflects your technical skills and interest in joining FIS as a software engineer. Whether you were contacted by a FIS recruiter or took the initiative yourself, carefully review the job description and tailor your CV according to the prerequisites.

Tailoring your CV may include identifying specific keywords that the hiring manager might use to filter resumes and crafting a targeted cover letter. Furthermore, don’t forget to highlight relevant skills and mention your work experiences.

Recruiter Screening

If your CV happens to be among the shortlisted few, a recruiter from the FIS Talent Acquisition team will make contact and verify key details like your experiences and skill level. They may ask questions such as "Why are you interested in FIS?" and "Why do you want to work for FIS?". Behavioral questions may also be a part of the screening process.

In some cases, several recruiters may participate during the screening round. They may also discuss salary expectations and other logistical details. However, it is important to note that some candidates have reported instances of being ghosted after this initial round, so make sure to follow up promptly and multiple times if needed.

Technical Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. This 1-hour long interview stage may involve basic coding assessments, scenario-based questions, and architecture-level discussions.

Questions might cover: - Basics and advanced level questions regarding programming languages like C/C++, SQL queries, joins, merge, etc. - Assessments on algorithms, project-related tasks, and coding problems (e.g., linked lists, arrays, binary trees). - Problem-solving and critical thinking scenarios.

Depending on the seniority of the position, further rounds could involve problem-solving on data structures and algorithms, discussed with senior technical team members via video conference or in-person.

Managerial and HR Interview

If you pass the technical interview, you will be invited for a managerial round. This stage typically focuses on architecture-level questions, behavioral questions, and an additional coding challenge. These interviews assess your understanding of project workflows, problem-solving skills, and your ability to fit within the company culture.

Questions may include: - Situational scenarios discussing past project experiences. - Technical discussions on architecture and design patterns. - Behavioral questions to evaluate motivation, stability, and team fit.

Followed by the technical and managerial rounds, you may undergo an HR interview to discuss salary expectations and other benefits.

Onsite or Final Rounds

After clearing the above stages, you would be invited for onsite interviews which could last for multiple rounds. Senior candidates sometimes present take-home assignments during this stage. The final decision usually takes a while due to internal reviews and potential management level changes.

• How would you design an A/B test to evaluate a pricing increase for a B2B SAAS company? A B2B SAAS company wants to test different subscription pricing levels. Design a two-week A/B test to evaluate a pricing increase and determine if it is a good business decision.

• How much should a ride-sharing app budget for a $5 coupon initiative? A ride-sharing app has a probability (p) of dispensing a $5 coupon to a rider and services (N) riders. Calculate the total budget needed for the coupon initiative.

• What is the probability of riders getting a coupon? A driver using the app picks up two passengers. Determine:

• The probability of both riders getting the coupon.

• The probability that only one of them will get the coupon.

• What is a confidence interval for a statistic and why is it useful? Explain what a confidence interval is, why it is useful to know the confidence interval for a statistic, and how to calculate it.

• What is the probability of finding an item on Amazon's website? Amazon has a warehouse system where items are located at different distribution centers. Given the probabilities that a specific item X is available at warehouse A (0.6) or warehouse B (0.8), calculate the probability that the item X would be found on Amazon's website.
