Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a time you had to follow detailed written instructions to complete a technical task.

What they are checking: Whether they read and follow procedures carefully, since block machining depends on every step in order.

Tell me about a time you made a mistake on a job. How did you handle it?

What they are checking: Whether they own and report errors quickly, which matters more in machining than never making one.

What would you do

You find a crack or defect in a block partway through the process. What do you do?

What they are checking: Whether they stop and report a defective core instead of finishing work on a part that will fail.

Your readings start drifting during a run and you're not sure if it's the tool or the part. How do you sort it out?

What they are checking: Whether they troubleshoot methodically by checking the tool first instead of guessing and continuing.

How do you keep up your pace on a fast line without cutting corners on quality?

What they are checking: Whether they can balance production numbers with accuracy, which is the daily tension on a block line.

About the work

Walk me through how you measure a cylinder bore with a bore gauge and micrometer.

What they are checking: Whether they can actually set and read precision tools, which is the heart of machining engine blocks to the correct value.

How do you know an engine block has been machined to the right value before it moves on?

What they are checking: Whether they verify their own work against the spec rather than assuming the machine got it right.

Before you start a procedure, how do you make sure you have every tool and material you need?

What they are checking: Whether they plan ahead so the line is not stopped while they hunt for a tool halfway through a job.

How do you care for precision tools so they stay accurate?

What they are checking: Whether they understand that a dropped or dirty gauge gives false readings and leads to bad blocks.

What production records have you kept before, and how do you make sure they're accurate?

What they are checking: Whether they record measurements, quantities and time honestly, since records are how quality problems get traced.
