Submitting Your Application

The first step in the Bentley Systems Software Engineer application process is to submit a compelling application that reflects your technical skills and interest in joining the company. Whether you were contacted by a Bentley Systems recruiter or have taken 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. Additionally, don’t forget to highlight relevant skills and mention your work experiences.

Recruiter/Hiring Manager Call Screening

If your CV happens to be among the shortlisted few, a recruiter from the Bentley Systems Talent Acquisition Team will make contact and verify key details like your experiences and skill level. Behavioral questions may also be a part of the screening process.

In certain cases, the Bentley Systems hiring manager may also be present during the screening round to answer queries about the role and the company itself. They might also indulge in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Technical Virtual Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the Bentley Systems Software Engineer role is generally conducted through virtual means, including video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around object-oriented programming, API design patterns, performance and scale, modern web, and desktop application architecture.

You may also be required to complete take-home assignments regarding code reviews, unit testing, and development using frameworks such as React, Angular, or Electron. Your proficiency in languages like C++, Java, or Rust and your ability to design secure software can also be assessed.

Onsite Interview Rounds

Following a second recruiter call outlining the next stage, you’ll be invited to attend the onsite interview loop. Multiple interview rounds, varying with the role, will be conducted during your day at the Bentley Systems office or virtually if the role is remote. Your technical prowess, including programming capabilities and system design skills, will be evaluated during these interviews.

If you were assigned take-home exercises, a presentation round may also await you during the onsite interview for the Software Engineer role at Bentley Systems.

Quick Tips For Bentley Systems Software Engineer Interviews

You should plan to brush up on any technical skills and try as many practice interview questions and mock interviews as possible. A few tips for acing your Bentley Systems interview include:

• Understand Bentley Systems' Products: Familiarize yourself with Bentley's innovative software solutions, their application in real-world projects, and their role in the global infrastructure sector.
• Programming Languages: Be proficient in languages relevant to the role, such as C++, C#, JavaScript, or TypeScript. Knowing the ins and outs of these languages can help you stand out.
• Demonstrate Team Collaboration: Bentley Systems values effective communication and collaboration among team members. Showcase your ability to work in a team with solid communication skills during behavioral interview questions.

Typically, interviews at Bentley Systems vary by role and team, but commonly Software Engineer interviews follow a fairly standardized process across these question topics.

• Write a SQL query to select the 2nd highest salary in the engineering department. Write a SQL query to select the 2nd highest salary in the engineering department. If more than one person shares the highest salary, the query should select the next highest salary.

• Write a function to merge two sorted lists into one sorted list. Given two sorted lists, write a function to merge them into one sorted list. Bonus: What's the time complexity?

• Create a function missing_number to find the missing number in an array. You have an array of integers, nums of length n spanning 0 to n with one missing. Write a function missing_number that returns the missing number in the array. Complexity of (O(n)) required.

• Develop a function precision_recall to calculate precision and recall metrics from a 2-D matrix. Given a 2-D matrix P of predicted values and actual values, write a function precision_recall to calculate precision and recall metrics. Return the ordered pair (precision, recall).

• Write a function to search for a target value in a rotated sorted array. Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. You are given a target value to search. If the value is in the array, return its index; otherwise, return -1. Bonus: Your algorithm's runtime complexity should be in the order of (O(\log n)).

• Would you think there was anything fishy about the results of an A/B test with 20 variants? Your manager ran an A/B test with 20 different variants and found one significant result. Would you suspect any issues with these results?

• How would you set up an A/B test to optimize button color and position for higher click-through rates? A team wants to A/B test changes in a sign-up funnel, such as changing a button from red to blue and/or moving it from the top to the bottom of the page. How would you design this test?

• What would you do if friend requests on Facebook are down 10%? A product manager at Facebook reports a 10% decrease in friend requests. What steps would you take to address this issue?

• Why might the number of job applicants be decreasing while job postings remain constant? You observe that the number of job postings per day has remained stable, but the number of applicants has been decreasing. What could be causing this trend?

• What are the drawbacks of the given student test score datasets, and how would you reformat them for better analysis? You have data on student test scores in two different layouts. What are the drawbacks of these formats, and what changes would you make to improve their usefulness for analysis? Additionally, describe common problems in "messy" datasets.

• Is this a fair coin based on 10 flips resulting in 8 tails and 2 heads? You flipped a coin 10 times, resulting in 8 tails and 2 heads. Determine if this outcome suggests the coin is fair.

• How would you write a function to calculate sample variance for a list of integers? Write a function that takes a list of integers and outputs the sample variance, rounded to 2 decimal places. For example, given test_list = [6, 7, 3, 9, 10, 15], the function should return 13.89.
