Walk me through your solids control career.
I've been in solids control for eight years, four in Oman. Started in field service at an Indian oilfield services firm, transitioned to sales engineering, and for the past three years I've been senior solids control sales engineer at a major service company in Oman. My remit: business development for solids control services with operators, technical proposals, account management. Petroleum engineering background plus commercial development.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a major win.
Last year I won a multi-rig contract with a major operator: technical solution that combined drilling waste management plus efficient solids control. Six months of pursuit including multiple technical workshops, pilot, commercial structuring. Contract over 3 years. Service company selling combines technical credibility plus commercial discipline.
Real sales delivery.
Describe a deal we lost.
Lost a deal at a target operator due to competitor's lower commercial. Maintained relationship; learned about their priorities for next opportunity; won subsequent engagement. Losing well preserves long-term relationships; losing badly damages them.
Loss handling.
Tell me about working with technical teams.
Operators' drilling fluids and drilling teams are technical buyers. I bring technical credibility from years of field experience. They engage technically rather than commercial-only. The combination wins where pure commercial sales fails.
Technical credibility.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through solids control fundamentals.
Drilling mud carries solids from drilling. Solids removal: shale shakers, desanders, desilters, centrifuges per particle size. Efficient solids control preserves mud quality, reduces dilution costs. Service quality matters across the drilling campaign.
Solids control depth.
Describe service offerings.
Equipment rental: shakers, centrifuges, mud cleaning units. Personnel: engineers and operators per rig. Performance contracts where service paid on outcome. Integration with broader fluids services. Service offerings designed per operator's specific needs.
Service depth.
How do you handle technical proposals?
Operator's well program understood. Service solution designed per well requirements. Performance targets agreed. Commercial structure aligned with risk and value. Technical credibility through detail. Proposals win on combination of technical fit and commercial competitiveness.

Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with operators?
Operators value reliability and field performance over sales talk. I'm honest on what we deliver; I don't oversell. I'm responsive on issues. Long-term relationships across rigs and engagements are the goal. Service company reputation is built across years.
Operator engagement.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior solids control sales engineer role at an Omani service company I'd target OMR 2,200 to 2,800 base plus commission depending on territory and account portfolio. OTE typically 30-50% on top for strong performance. I'd expect car allowance and entertainment budget. I'm on 60 days' notice. Beyond pay I'd value the service portfolio and technical depth.
