Interviewers look for candidates who can connect data points to physical assets and operational workflows.

Data Storytelling & Visualization – It is not enough to run queries; you must be able to explain what the numbers mean. Practice structuring your findings into clear, visual narratives. Be prepared to explain how you design dashboards that empower busy operational managers to make quick decisions.

Stakeholder Management – You will collaborate with immediate managers, plant directors, and corporate executives. You must demonstrate that you can build trust, gather requirements effectively, and communicate insights clearly across different levels of the organization.

Resilience & Communication Agility – The corporate environment can move fast, and priorities may shift. Show that you can remain objective, manage your time effectively, and maintain clear lines of communication even when project timelines or scopes are ambiguous.

The interview process for a Data Analyst at OTIS is designed to be highly structured, objective, and collaborative. Candidates can expect a multi-stage process that evaluates both technical capabilities and cultural fit within the industrial operations environment.

The journey typically begins with an HR screening, which focuses on your background, career motivations, and alignment with OTIS values. This is followed by interviews with your immediate manager (gestor imediato) and senior leadership, which often includes the plant manager (gerente da planta) or regional operations director. These discussions are highly practical, focusing on the actual deliverables of the role and the daily challenges of the specific plant or department.

The evaluation focuses heavily on clarity and realism. The interviewers will be very transparent about the scope of work, the daily challenges, and what is expected of you in your first few months. This transparency ensures that you can enter the role with a clear understanding of your key deliverables.

The timeline above outlines the typical progression from the initial contact to the final decision. Candidates should use this visual guide to pace their preparation, ensuring they focus on high-level background alignment early on, and transition to deep technical and operational scenario preparation for the hiring manager and plant manager rounds.

To succeed in the OTIS interview process, you must perform exceptionally well across several core competencies. Understanding these areas in detail will allow you to tailor your preparation effectively.

Operational Data & KPI Formulation

OTIS relies on precise metrics to keep manufacturing plants and service networks running smoothly. You will be evaluated on your ability to define, calculate, and interpret key operational metrics.

Be ready to go over:

• Throughput & Capacity Analytics – Understanding how to measure and optimize production output within a physical plant.

As a Data Analyst at OTIS, your day-to-day activities will center around transforming raw industrial data into strategic business value. You will be embedded closely with operational teams, ensuring that your analytical output directly supports physical workflows.

Your primary responsibility will be the development, maintenance, and optimization of operational dashboards. You will work closely with plant managers and immediate supervisors to understand their tracking needs, building automated reporting systems that monitor daily production, safety metrics, and supply chain efficiency. This requires regular data extraction from central databases and ERP systems, followed by rigorous data cleaning and modeling.

Beyond routine reporting, you will conduct ad-hoc deep-dive analyses to solve specific operational challenges. For instance, if a manufacturing plant experiences unexpected downtime or a service region sees a spike in elevator call-backs, you will be tasked with investigating the underlying data to identify patterns and root causes. You will then present these findings directly to area managers, providing clear, actionable recommendations to improve performance.

Collaboration is a cornerstone of this role. You will act as the analytical bridge between technical IT infrastructure teams and the hands-on operations staff. This means you must comfortably navigate technical database environments while remaining highly accessible and communicative with factory floor supervisors and business leaders who rely on your insights.

To be competitive for the Data Analyst position at OTIS, candidates must demonstrate a strong foundation in data analytics alongside an understanding of industrial operations.

• Technical Skills – Proficiency in SQL for data extraction and manipulation is essential. You must have strong hands-on experience building dashboards in Power BI or Tableau. Advanced Excel skills (including Power Query and pivot tables) are required, as many legacy workflows still utilize spreadsheet-based tracking.
• Experience Level – Typically, OTIS looks for candidates with 2 to 5 years of experience in data analytics, business intelligence, or industrial engineering. Experience working within manufacturing, logistics, supply chain, or field service industries is highly valued.
• Soft Skills – Strong communication is a must-have. You must be able to present data clearly to both technical and non-technical audiences. A proactive approach to problem-solving and the ability to work independently in a fast-paced environment are critical.

Must-have skills:

• Strong SQL querying skills and experience with relational databases.
• Proven expertise in data visualization tools, specifically Power BI.
• Excellent communication skills with the ability to interface with plant-level management.

Nice-to-have skills:

• Experience with SAP or other major ERP systems.
• Knowledge of Python or R for advanced statistical analysis.
• Background in Lean Manufacturing or Six Sigma methodologies.
