help me prep for this intervew https://www.linkedin.com/jobs/view/4452672926/

I would love to help you prep for this Senior Business Analyst role! To make sure we tailor our mock scenarios and technical practice perfectly to what they are looking for, let's start with a quick question.

To help us tailor this interview prep, when is your interview scheduled, and are there specific topics or types of questions (e.g., technical SQL, behavioral STAR stories, case scenarios) you want to focus on most?

No date set yet, just getting started. I want a comprehensive review of everything.

A comprehensive review is a smart move, especially for a heavy-hitting role like this one at Roche! Let's kick off our prep by laying out our master plan to cover every angle of your upcoming preparation.

Our very first destination is Requirement Gathering and Agile Methodologies. In a senior role, you aren't just taking down orders; you are translating messy human needs into structured, technical blueprints. To do this, senior analysts rely on two key types of documentation to align business teams with developer teams: Business Requirement Documents (BRDs) and Functional Requirement Documents (FRDs). While they sound similar, they serve entirely different audiences. Let's look at how they compare side-by-side:

Feature	Business Requirement Document (BRD)	Functional Requirement Document (FRD)
The Core Question	Why are we building this, and what is the business value?	How will the system actually behave to make this happen?
Primary Audience	Business executives, clients, and project sponsors.	Software developers, system architects, and QA engineers.
Technical Depth	High-level business goals, scope, and process maps.	Detailed technical specifications, data rules, and system logic.
Ownership	Written primarily by the Lead or Senior BA.	Collaboratively written by the BA and Technical Architects.

To make this concrete, imagine Roche wants to build a new digital that allows clinical researchers to securely share genetic data sets. The BRD would state the high-level business case: "The platform must comply with global genomic data privacy laws while reducing researcher data-sharing time by 40%." The FRD gets into the technical gears. It would detail the exact security specifications: "When a user uploads a dataset, the system must encrypt the file using AES-256 and auto-generate an audit log entry within 500 milliseconds." Do you see how the BRD sets the target, and the FRD maps out the actual system mechanics?
