Interview scorecard template

Telecommunications Analyst interview scorecard

Evaluate Telecommunications Analyst candidates across 4 weighted areas: technical depth, work that shipped, diagnosis under uncertainty, and working across the org. Technical depth leads at 35%, so check command of SIP signalling, MPLS and SD-WAN circuits, PBX or UCaaS platforms (Cisco CUCM, Avaya, Teams Voice), plus carrier tariffs, DIDs, E911 and SIP. Use the rubric to compare role-specific evidence consistently.

TL;DR
For technical depth, look for evidence the candidate reads SIP ladder diagrams and Wireshark captures fluently, explains Erlang B trunk sizing and codec choice with real numbers. For work that shipped, look for evidence the candidate names specific migrations and sites, cites recovered telecom spend, ported number counts and cutover dates with minimal user disruption. Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it

Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.

01
Evaluation factor

Technical depth

35% weight

Check command of SIP signalling, MPLS and SD-WAN circuits, PBX or UCaaS platforms (Cisco CUCM, Avaya, Teams Voice), plus carrier tariffs, DIDs, E911 and SIP trunk sizing.

Evidence to listen for

  • Explains the physics or mechanism behind their work, not just the tooling
  • Names the standards, tolerances, and constraints they designed against
  • Can defend a design decision under follow-up questions
  • Distinguishes what they personally engineered from what the team delivered

Five-point scoring guide

1
Poor

Cannot explain the fundamentals of their own stated specialism.

2
Needs Improvement

Knows the vocabulary but not the underlying mechanism; struggles under follow-ups.

3
Satisfactory

Solid working knowledge for the role; depth thins out on edge cases.

4
Very Good

Strong command of the domain; explains trade-offs and defends decisions well.

5
Excellent

Reads SIP ladder diagrams and Wireshark captures fluently, explains Erlang B trunk sizing and codec choice with real numbers.

02
Evaluation factor

Work that shipped

30% weight

Ask what they delivered: site cutovers, PRI to SIP migrations, carrier contract renegotiations, MACD volumes handled, or invoice audits that recovered spend.

Evidence to listen for

  • Names specific programmes, parts, or systems that reached production or field use
  • States their own scope inside the project
  • Can give measured outcomes: yield, cycle time, cost, failure rate
  • Explains what went wrong and what they changed

Five-point scoring guide

1
Poor

No delivered work; experience is coursework, lab-only, or purely observational.

2
Needs Improvement

Contributed to projects but cannot say what shipped or what their part was.

3
Satisfactory

Has delivered real work; outcomes described without numbers.

4
Very Good

Names shipped work and their scope, with some measured results.

5
Excellent

Names specific migrations and sites, cites recovered telecom spend, ported number counts and cutover dates with minimal user disruption.

03
Evaluation factor

Diagnosis under uncertainty

20% weight

Probe how they isolate one-way audio, jitter and dropped calls across LAN, firewall SBC and carrier boundaries, and when they escalate to the provider with evidence.

Evidence to listen for

  • Describes a real failure they chased to root cause
  • Shows a method: isolate variables, reproduce, measure, eliminate
  • Distinguishes correlation from cause
  • Says what they ruled out and why, not only what the answer turned out to be

Five-point scoring guide

1
Poor

No diagnostic method; guesses or escalates immediately.

2
Needs Improvement

Trial and error with no structure; cannot explain how they narrowed the cause.

3
Satisfactory

Reasonable method on familiar problems; less structured on novel ones.

4
Very Good

Clear systematic approach with a real root-cause story.

5
Excellent

Walks a real fault from complaint to root cause using CDRs, MOS scores and packet captures, ruling out layers methodically.

04
Evaluation factor

Working across the org

15% weight

Assess how they work with network, security, facilities and finance teams: change windows, carrier account managers, purchase orders and end-user training on new handsets.

Evidence to listen for

  • Explains technical constraints to non-technical stakeholders without condescension
  • Has negotiated scope, cost, or timeline with manufacturing, product, or suppliers
  • Documents decisions so others can act on them
  • Takes review feedback without defensiveness

Five-point scoring guide

1
Poor

Cannot communicate outside their specialism; dismissive of other functions.

2
Needs Improvement

Communication gaps cause rework; avoids stakeholder contact.

3
Satisfactory

Works adequately with other teams; documentation is thin.

4
Very Good

Communicates clearly across functions; reliable collaborator.

5
Excellent

Describes coordinating vendors and internal teams through change control, translating circuit detail into plain terms for finance and leadership.
