Cepheid is a global innovator in automated molecular diagnostics and PCR technology. Powered by its flagship GeneXpert® System and Xpert® test menu, Cepheid delivers real-time, scalable diagnostic results across critical healthcare areas including oncology, sexual health, virology, respiratory infections, and healthcare-associated infections. Cepheid operates as part of Danaher Corporation’s Diagnostics segment.

This internship challenge hires directly into the Danaher India Development Center (IDC) in Bangalore (a 120k sq. ft. state-of-the-art facility housing 900+ R&D associates). The software engineering team at IDC drives cloud informatics, data analytics, and embedded/enterprise software platforms that power cutting-edge diagnostic instruments in collaboration with global R&D centers in the US, France, Germany, Japan, Denmark, and Sweden.

The assessment is conducted online via HackerEarth (Webcam proctored) with a total duration of 2 Hours 15 Minutes:

Note on Coding Environment: Java is the mandatory programming language for the coding section. Code execution is judged based on runtime time limits (TLE), memory limits (MLE), and strict output formatting against hidden test cases on HackerEarth’s judge.

1. Angular Framework (MCQ Preparation)

• Components & Templates: Data binding (one-way, two-way ngModel), Event binding, Property binding, and Lifecycle hooks (ngOnInit, ngOnChanges, ngOnDestroy).
• Services & Dependency Injection: Injectable services, singleton instances, module providers (providedIn: 'root').
• Directives & Pipes: Structural directives (*ngIf, *ngFor, *ngSwitch), attribute directives, and custom pipe creation.
• RxJS & Async Operations: Observables vs. Promises, RxJS operators (map, filter, switchMap, mergeMap), and AsyncPipe.

2. Java & DSA (Coding Preparation)

• Core Java Mechanics: Standard I/O parsing using Scanner / BufferedReader, Collections Framework (ArrayList, HashMap, HashSet, PriorityQueue), String manipulation, and Exception Handling.
• Basic Algorithms: Sliding Window technique, Two Pointers, Array manipulation, Binary Search, String reversal/patterns, and Hash Table lookup strategies.

• SIGSEGV (Segmentation Fault): Out-of-bounds array indexing or null object dereferencing in Java.
• NZEC (Non-Zero Exit Code): Uncaught runtime exceptions (e.g., NullPointerException, ArrayIndexOutOfBoundsException). Always handle edge cases.
• TLE (Time Limit Exceeded): Ensure algorithm complexity fits within the 1.0–2.0 second execution window (use $O(N)$ or $O(N \log N)$ approaches instead of $O(N^2)$ brute force).
• Output Formatting: Do not print extraneous debugging statements (e.g., "Enter value:"). Output exact results matching the required test case format.
