What a hiring manager scans for in 15 seconds
Hiring managers quickly assess if you understand the business impact of your technical decisions. They look for evidence that you can translate technical jargon into business outcomes.
- Impact: Can you quantify your contributions in terms of revenue, cost savings, or efficiency gains?
- Stakeholders: Do you understand the needs and priorities of different stakeholders?
- Tradeoffs: Can you articulate the tradeoffs you made and why you made them?
- Risk: Do you proactively identify and mitigate risks?
- Communication: Can you communicate clearly and concisely, both verbally and in writing?
- Artifacts: Can you show examples of your work, such as diagrams, reports, or code?
The mistake that quietly kills candidates
Failing to quantify your impact is a silent killer. Vague descriptions like “improved performance” don’t cut it. You need to provide concrete metrics and demonstrate how your work contributed to the bottom line.
Use this when updating your resume.
Weak: Improved system performance.
Strong: Reduced system latency by 15% (measured via Datadog) resulting in a 5% increase in transaction throughput, improving customer satisfaction (NPS score +8).
Mistake #1: Ignoring the Business Context
IT Engineers sometimes get lost in the technical details and forget the bigger picture. They implement solutions without understanding the business needs or how their work contributes to the overall goals of the organization.
For example, an IT Engineer might spend weeks optimizing a database query that only saves a few milliseconds, while ignoring a critical security vulnerability that could expose the company to a data breach. In manufacturing, this may look like focusing on automating a low-value process instead of improving uptime on a critical machine.
Fix: Before starting any project, take the time to understand the business context. Talk to stakeholders, review business requirements, and make sure your work is aligned with the organization’s goals.
Mistake #2: Neglecting Security
Security is often treated as an afterthought, rather than an integral part of the IT Engineer process. This can lead to vulnerabilities that can be exploited by attackers.
An IT Engineer at a Fintech company might deploy a new application without properly configuring access controls, allowing unauthorized users to access sensitive data. Or, they fail to patch a known vulnerability in a critical system, leaving it open to attack. A healthcare IT Engineer could expose patient data by failing to encrypt data at rest.
Fix: Make security a priority from the beginning. Follow security best practices, conduct regular security audits, and train your team on security awareness.
Mistake #3: Poor Communication
IT Engineers often struggle to communicate effectively with non-technical stakeholders. They use jargon, fail to explain technical concepts in plain language, and don’t keep stakeholders informed of progress.
Imagine an IT Engineer trying to explain a complex system outage to the CFO. If they use technical terms like “network partitioning” and “Byzantine fault tolerance,” the CFO will likely tune out and become frustrated. A better approach is to explain the impact in business terms, such as “the outage prevented customers from placing orders, resulting in a $50,000 loss in revenue.”
Fix: Learn to communicate clearly and concisely. Use plain language, avoid jargon, and tailor your communication to your audience.
Mistake #4: Ignoring Documentation
Documentation is often seen as a chore, rather than a valuable asset. IT Engineers neglect to document their work, making it difficult for others to understand and maintain the systems they build. This is a silent red flag during hiring.
For example, an IT Engineer might deploy a complex application without documenting the configuration settings, dependencies, or troubleshooting steps. When the system fails, it can take hours or even days to figure out what went wrong. In a manufacturing plant, this might mean no documentation on how a custom machine was built or how to repair it.
Fix: Document everything. Use a consistent documentation format, keep your documentation up-to-date, and make it easily accessible to others.
Mistake #5: Lack of Monitoring and Alerting
IT Engineers often fail to implement adequate monitoring and alerting systems. This makes it difficult to detect and respond to problems before they impact users.
An IT Engineer might deploy a new application without setting up proper monitoring, so they don’t realize that the system is experiencing high latency until users start complaining. Or, they might set up alerts that are too sensitive, resulting in alert fatigue and missed critical issues. In transportation, this might mean not monitoring the location of critical shipments.
Fix: Implement comprehensive monitoring and alerting systems. Set up alerts for critical metrics, tune your alerts to minimize false positives, and respond to alerts promptly.
Mistake #6: Over-Engineering Solutions
IT Engineers sometimes over-engineer solutions, making them more complex than necessary. This can lead to increased costs, longer development times, and systems that are difficult to maintain.
An IT Engineer might use a complex microservices architecture for a simple application that could be easily implemented with a monolithic architecture. Or, they might choose a cutting-edge technology that is not well-suited for the task at hand. A government IT Engineer could introduce unnecessary complexity to a system due to personal preference.
Fix: Keep it simple. Choose the simplest solution that meets the requirements.
Mistake #7: Not Testing Thoroughly
Testing is often rushed or skipped altogether. This can lead to bugs and other issues that can impact users.
An IT Engineer might deploy a new application without conducting thorough testing, resulting in a critical bug that prevents users from logging in. Or, they might only test the happy path, ignoring edge cases and error conditions. A retail IT Engineer might deploy code that breaks the checkout process.
Fix: Test everything thoroughly. Use a variety of testing methods, including unit testing, integration testing, and user acceptance testing.
Mistake #8: Poor Change Management
Changes are often made without proper planning or communication. This can lead to unexpected outages and other problems.
An IT Engineer might deploy a new version of an application during peak hours, resulting in a system outage that impacts thousands of users. Or, they might make a change without notifying stakeholders, leading to confusion and frustration. A logistics IT Engineer might break the shipping system by pushing untested code.
Fix: Implement a robust change management process. Plan your changes carefully, communicate them to stakeholders, and test them thoroughly before deploying them to production.
Mistake #9: Neglecting Vendor Management
Vendors are often not properly managed, leading to missed deadlines, poor quality, and cost overruns. A Vendor Management Rubric can help mitigate this.
An IT Engineer might outsource a critical project to a vendor without properly vetting their capabilities, resulting in a project that is delivered late, over budget, and with poor quality. Or, they might fail to enforce the terms of the contract, allowing the vendor to get away with substandard performance. A construction IT Engineer might not properly vet a vendor managing the security cameras.
Fix: Manage your vendors closely. Set clear expectations, monitor their performance, and hold them accountable for their results.
Use this to evaluate vendor performance.
Vendor Management Rubric
- Technical Expertise: Does the vendor have the necessary technical skills and experience? (Weight: 25%)
- Communication: Does the vendor communicate clearly and effectively? (Weight: 20%)
- Project Management: Does the vendor manage projects effectively? (Weight: 20%)
- Quality: Does the vendor deliver high-quality work? (Weight: 20%)
- Cost: Is the vendor cost-effective? (Weight: 15%)
Mistake #10: Ignoring Performance Tuning
Systems are often deployed without proper performance tuning, leading to slow response times and poor user experience.
An IT Engineer might deploy a new application without optimizing the database queries, resulting in slow response times that frustrate users. Or, they might fail to configure the web server properly, leading to high CPU utilization and poor performance. A cloud IT Engineer might not properly size instances leading to poor performance.
Fix: Tune your systems for optimal performance. Use performance monitoring tools to identify bottlenecks, optimize database queries, and configure your web servers properly.
Mistake #11: Scope Creep
Projects often suffer from scope creep, leading to missed deadlines and budget overruns. Projects can get off track by adding features that weren’t originally planned.
An IT Engineer might agree to add a new feature to a project without properly assessing the impact on the schedule and budget. Or, they might fail to manage stakeholder expectations, leading to a constant stream of new requests. A marketing IT Engineer might agree to changes to the website without understanding the impact on other projects.
Fix: Manage scope carefully. Document all requirements, assess the impact of any new requests, and communicate any changes to stakeholders.
Here’s a 10-step change control process:
- Identify the change: Document the proposed change.
- Assess the impact: Evaluate the impact on scope, schedule, and budget.
- Obtain approval: Get approval from stakeholders.
- Update the project plan: Incorporate the change into the project plan.
- Communicate the change: Notify stakeholders of the change.
- Implement the change: Make the necessary changes to the system.
- Test the change: Verify that the change works as expected.
- Deploy the change: Deploy the change to production.
- Monitor the change: Monitor the impact of the change.
- Document the change: Update the documentation to reflect the change.
Mistake #12: Failing to Learn from Mistakes
IT Engineers often repeat the same mistakes over and over again. They don’t take the time to analyze their failures and learn from them.
An IT Engineer might experience a system outage due to a configuration error, but they don’t take the time to document the root cause and implement preventative measures. As a result, they make the same mistake again in the future. A sales IT Engineer might make a mistake in setting up a new CRM and then repeat that error.
Fix: Learn from your mistakes. Conduct post-mortem analyses after every project, document the lessons learned, and implement preventative measures.
