Submitting Your Application

The first step is to submit a compelling application that reflects your technical skills and interest in joining Consultadd as a Software Engineer. Whether you were contacted by a Consultadd 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. Furthermore, 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 Consultadd 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 some cases, the Consultadd Software Engineer hiring manager stays present during the screening round to answer your queries about the role and the company itself. They may 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 Consultadd Software Engineer role is usually conducted through virtual means, including video conference calls and screen sharing. Questions in this 1-hour long interview stage may revolve around data structures and algorithms (DSA), computer science (CS) fundamentals, and project-related questions.

• Typical DSA problems include:
• Subset sum problem
• Implementing a queue using stacks in Java

• Sorting 0, 1, 2 without using a sorting algorithm

• Additional technical topics:

• OOP concepts like polymorphism, inheritance, and abstraction
• SQL queries, often combining multiple tables
• Core CS subjects such as operating systems (OS), computer networks (CN), and database management systems (DBMS)

Onsite Interview Rounds

Followed by 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 Consultadd. Your technical prowess, including programming and problem-solving capabilities, will be evaluated against the finalized candidates throughout these interviews.

There are generally three rounds during the onsite interview:

1. First Technical Interview: Covers basic core CS subjects like OS, DBMS, CN, and Data Structures.
2. Second Technical Interview: Focuses on advanced DSA problems, project discussion, and additional SQL queries.
3. HR Interview: A typical HR round to discuss your background, expectations, and a fitment check.

Quick Tips For Consultadd Software Engineer Interviews

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

• Strong Foundation in DSA and SQL: Ensure you are well-versed in data structures, algorithms, and SQL queries. Practice medium to hard-level problems to stay prepared.
• Core CS Fundamentals: Brush up on core computer science subjects such as operating systems, computer networks, and database management systems.
• Understand OOP Concepts: Be clear on object-oriented programming principles like polymorphism, inheritance, and abstraction as these are frequently discussed topics.

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

• Would you suspect anything unusual about the A/B test results with 20 variants? Your manager ran an A/B test with 20 different variants and found one significant result. Would you consider this result suspicious?

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

• Why might the number of job applicants be decreasing despite stable job postings? You observe that the number of job postings per day has remained constant, but the number of applicants has been steadily 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 issues in "messy" datasets.

• Is this a fair coin? You flip a coin 10 times, and it comes up tails 8 times and heads twice. Determine if the coin is fair based on this outcome.

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

• Is there anything suspicious about the A/B test results? Your manager ran an A/B test with 20 different variants and found one significant result. Would you find anything suspicious about these results?

• How would you find the median in (O(1)) time and space? Given a list of sorted integers where more than 50% of the list is the same repeating integer, write a function to return the median value in (O(1)) computational time and space. For example, given li = [1,2,2], the function should return 2.

• What are the drawbacks of the given data organization, and how would you reformat it? Assume you have data on student test scores in the layouts shown in Dataset 1 and Dataset 2. Identify the drawbacks of this organization, suggest formatting changes to make the data more useful for analysis, and describe common problems seen in "messy" datasets.

• How would you evaluate whether using a decision tree algorithm is the correct model for predicting loan repayment? You are tasked with building a decision tree model to predict if a borrower will pay back a personal loan. How would you evaluate if a decision tree is the right choice, and how would you assess its performance before and after deployment?

• How does random forest generate the forest, and why use it over logistic regression? Explain the process by which a random forest generates its ensemble of trees. Additionally, discuss the advantages of using random forest over logistic regression.

• When would you use a bagging algorithm versus a boosting algorithm? Compare two machine learning algorithms. Describe scenarios where you would prefer a bagging algorithm over a boosting algorithm, and discuss the tradeoffs between the two.

• How would you justify using a neural network for a business problem and explain its predictions to non-technical stakeholders? Your manager asks you to build a neural network model to solve a business problem. How would you justify the complexity of the model and explain its predictions to non-technical stakeholders?

• What metrics would you use to track the accuracy and validity of a spam classifier? You are tasked with building a spam classifier for emails and have completed a V1 of the model. What metrics would you use to evaluate the model's accuracy and validity?

• Implement a function to find the shortest path in a graph using any shortest path algorithm. You are given a graph represented as a 2D array where each cell value indicates the cost to traverse to that node. Also given are a start node and an end node. Your task is to find the shortest path from the start node to the end node.
