I applied online. I interviewed at Enosis Solutions (Bangladesh) (Dhaka) in Jan 2026
Interview
Round 1: Online Screening & Coding TestFormat: Conducted online via platforms like HackerRank or a shared document without an IDE.Duration: Ranges from a quick 15-minute screening to a 60–90 minute comprehensive exam.Content: Typically includes 2 Data Structures and Algorithms (DSA) problems, 1 SQL query, and 4–6 analytical or aptitude multiple-choice questions.Problems: Range from easy array manipulation to LeetCode Medium questions like mirror rotation or process queues.Environment: Monitored closely, often recorded, and AI tools are strictly prohibited.Round 2: Live Technical InterviewFormat: A 1-hour live session conducted over video call using a shared document.Content: Consists of 2–3 coding questions lasting about 20 minutes each.Topics: Focuses on recursion, string operations (like text justification), stacks, graphs, and building hierarchical tree views.Expectations: Candidates must explain their thought process, analyze time and space complexities, and discuss alternative solutions.
Interview questions [1]
Question 1
Problem Statement:You are given an array of objects where each object represents a node. Each node has an id, a name, and a parentId. If the parentId is null, it means the node is the root. Write a function to transform this flat array into a deeply nested tree structure.

Interview
80 minute online screening test. 2 problem solving, 1 sql, 4 mcq question about iq or math. Then technical interview 1 vs 1 in online (1.5 hour). Discuss about project and new problem solving.
The first round was an online coding round. I applied through the campus recruitment process. The online coding test was taken on HackerRank. There were 7 questions in total. From problem-solving, SQL, and basic analytic problems. 80 minutes was given for solving all these.
There are three rounds in total. The first one is a technical coding round. The test is around 90 minutes. Its a mix of coding problems, SQL and analytical MCQs.
