APT Portfolio Career Page LinkedIn APT Portfolio Eligibility Criteria for Engineering Roles APT Portfolio seeks candidates for engineering roles with specific qualifications, particularly for freshers in software development and quantitative positions: B.E./B.Tech in Computer Science, Computer Science Engineering, or related fields; advanced degrees like M.Tech preferred. Strong academic record with a resume highlighting relevant skills in programming and algorithms. For freshers, no prior experience required; emphasis on problem-solving, projects, and technical aptitude. APT Portfolio Recruitment Process: Selection Rounds APT Portfolio’s hiring process for engineering roles typically involves 3-5 rounds, depending on the role and recruitment drive (campus, off-campus, or hiring challenges). The process is conducted via platforms like HackerRank or Zoom, focusing on coding proficiency, technical depth, and cultural fit. Online Assessment (Aptitude/Coding) An initial screening lasting 60-90 minutes, often split into two parts: Aptitude Section : 20-30 MCQs on quantitative ability, logical reasoning, and CS fundamentals (OOPS, DBMS, OS, networks). Coding Section : 2-3 coding problems (e.g., linked list operations, tree traversals) testing efficiency in C++, Python, or Java. Problems may include n-th node in a linked list or leaders in an array. Technical Round-1 A virtual interview focusing on Data Structures and Algorithms (DSA). Candidates solve 1-2 problems (e.g., intersection of sorted linked lists, top view of a binary tree) on a shared screen, with questions on time/space complexity. Discussions cover OOPS, basic networking, and resume-based projects.

For HFT roles, system design for trading platforms or optimization questions may arise. Technical Round-3 (Optional) For Quantitative Developer or senior roles, an additional round may focus on system design (e.g., low-latency trading systems), advanced algorithms, or probability/statistics for trading strategies. This round is more common in off-campus or experienced hires.

HR Round A behavioral interview assessing fit for APT’s meritocratic culture. Questions include “Why APT Portfolio?”, strengths/weaknesses, teamwork scenarios, and motivation for high-frequency trading. Background verification and salary discussions conclude the process.
