Why pre-screen RPA developers before the technical interview
RPA has an unusually visible failure mode: a bot that works for six weeks, then breaks when a vendor updates their interface, and costs more in maintenance than the manual process it replaced. Developers who have supported bots in production design differently, using selectors that survive layout changes, exception handling that raises rather than swallows, and a refusal to automate processes that were about to change. None of that is visible in a portfolio of delivered automations.
What actually matters when screening Robotic Process Automation (RPA) Developer candidates
- 01
Technical proficiency
Check hands-on depth in UiPath, Power Automate or Blue Prism: REFramework, selectors and dynamic UI, queue design, orchestrator triggers, plus C# or Python custom activities.
- 02
Systems and trade-offs
Probe how they choose attended versus unattended bots, when API or SQL integration beats UI automation, and how they handle credential vaults and licence cost.
- 03
Evidence and rigour
Assess measured outcomes: hours saved, transaction success rate, exception ratios, and how they proved handling time before and after via process mining or log analysis.
- 04
Collaboration and communication
Look for evidence of running process walkthroughs with business SMEs, producing PDDs and SDDs, and handling UAT sign-off plus hypercare after go-live.
Pre-screening questions to ask Robotic Process Automation (RPA) Developer candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Platform and scripting depth
3 questions01Can you describe your experience with RPA tools such as UiPath, Blue Prism or Automation Anywhere?
Listen forOne platform with real production depth and an honest level on the others, plus what that platform handles badly in their experience.
Claims equal expertise across all major platforms, or names a tool with no bot they took to production on it.
02What is your experience with scripting languages such as Python or JavaScript in an RPA context?
Listen forCode written where the visual designer ran out, with a specific problem it solved that could not be built through the interface.
Avoids anything outside drag and drop, or claims scripting with no example of where they needed it.
03Have you integrated RPA solutions with systems such as ERP, CRM or databases?
Listen forAPI or database integration used in preference to screen interaction where available, with a reason for each choice they made.
Automates through the user interface even where an API exists, with no awareness of the fragility that introduces.
Choosing what to automate
3 questions04How do you approach process mapping and documentation before starting an RPA project?
Listen forTime spent observing the process as performed rather than as documented, with the undocumented exceptions found before the build started.
Builds from a written process document alone, or discovers the exceptions only after the bot goes live.
05How do you assess the return on an RPA implementation?
Listen forHours saved measured against build and ongoing maintenance cost, with honesty about a bot whose maintenance outweighed the benefit.
Counts hours saved with no maintenance cost included, or return calculated once and never revisited.
06How do you handle process changes or updates to a well-established RPA workflow?
Listen forA change process with impact assessment and testing, plus a case where an upstream system change broke a bot and how they found out.
Changes applied directly in production, or breakages discovered only when a business user reported the output was wrong.
Exceptions and resilience
3 questions07Can you give examples of how you have handled error handling and exceptions in your RPA solutions?
Listen forBusiness and system exceptions handled separately, with failures raised to a person rather than swallowed, and partial work rolled back cleanly.
Wraps everything in a catch-all that suppresses errors, or bots that fail silently and leave transactions half complete.
08What debugging techniques do you use when an RPA workflow goes wrong?
Listen forLogging designed in from the start, with a specific intermittent failure they traced through timing or a selector that matched inconsistently.
Debugs by rerunning until it works, or has no logging beyond whether the bot completed.
09What steps do you take to protect sensitive data within an RPA solution?
Listen forCredentials held in a vault rather than in the workflow, with logging that avoids recording personal data and access limited by bot identity.
Credentials stored in the workflow or in configuration files, or full screen captures logged including personal data.
Working with process owners
3 questions10Can you discuss a challenging RPA project and how you overcame the obstacles?
Listen forA genuine obstacle such as an unstable source system or a process that varied by operator, with what they changed rather than worked around.
Difficulty described only as scope or timeline, or obstacles resolved by narrowing the automation until it was trivial.
11How do you manage version control and deployment of RPA bots?
Listen forSource control with separate environments and a rollback path, plus how they coordinate a release with the team whose process it runs.
Edits bots directly in production, or no environment separation between development and live running.
12Can you describe your experience with Agile or Scrum methodologies in RPA projects?
Listen forProcess owners involved during the build rather than at handover, with a requirement that changed because someone watched a demonstration early.
Delivers against a signed specification with no contact with the people performing the process.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Technical proficiency
35%5Names specific frameworks and activities, explains selector repair, queue retry logic and custom library code they built rather than reused.
Systems and trade-offs
25%5Rejects unsuitable processes outright, argues for API-first where available, and sizes bot count against volume, SLA and licence spend.
Evidence and rigour
25%5Quotes baseline versus post-automation metrics, cites exception rates from Orchestrator logs, and distinguishes claimed savings from audited ones.
Collaboration and communication
15%5Describes PDD workshops with named business functions, negotiated scope changes, and support handover documentation that operations staff actually used.
A bot that breaks on the next interface update costs more than the process it replaced. A one-way video screen lets you hear whether a candidate builds for change.

Process basics
How long should a pre-screening round for an RPA developer take?
Fifteen minutes across eight to ten questions, answered async. Enough to confirm which platforms they have shipped on, hear how they handle exceptions, and find out whether they supported their bots after go-live.
How much traditional coding should an RPA developer have?
Enough to leave the visual designer when it runs out. Expect working knowledge of a scripting language, APIs and databases. Developers who cannot go beyond drag and drop build the fragile screen-scraping bots that generate the maintenance problem.
Evaluating answers
What is the strongest signal when screening an RPA developer?
A bot that broke and why. Developers who have supported production describe the interface change, the selector strategy that failed, and what they did to make it resilient. Candidates who only deliver projects have never seen their work degrade.
How do I check they can choose the right processes?
Ask what they have refused to automate. A developer with judgement can name a process that was unstable, low volume, or due to be replaced by a system change. Anyone who automates whatever is requested will build bots that are obsolete on delivery.
