No matter what kind of interview, the questions asked are similar, and there are rules to be found. In fact, for all interviewers, there is only one purpose: to get the most information about you in the shortest time. If you want to prepare for an interview efficiently, start from the following seven aspects!
Basic information: Please describe your previous work experience and achievements in the most concise language.
Professional background: What qualities do you think this position should have?
Working Mode: Are you used to working alone or as a team?
Value Orientation: What do you think of your former employer and boss?
Qualifications: How would you describe your personality?
Salary: Can you tell me your salary now?
Background investigation: Do you mind if we conduct some investigation through your original unit?
Most interviews are basically inseparable from these questions. Of course, you can also ask some professional questions. For example, when you are in IOQC position, you will generally ask questions to job seekers from the aspects of IPQC purpose, IPQC method, IPQC process inspection work content and job responsibilities. Therefore, job seekers who ask professional questions can make the following preparations:
IPQC purpose
The process of product realization is a complex human-computer interaction system, which consists of different processes. In this process, there is both logistics and information flow. In order to make the output meet customer requirements, the following aspects must be achieved:
Ensure input quality
Machinery and equipment are stable and fully capable, and personnel work in strict accordance with standards.
The key parameter (CTQ) closely related to product quality is in a stable and controlled state.
The information is accurate, complete and timely, which can play a guiding role.
An effective process monitoring mechanism can detect process anomalies in time.
Feedforward mechanism enables the process to correct anomalies in time.
The reverse feedback mechanism can effectively prevent bad drainage.
Review the initial and final parts of products and provide shift quality assurance.
Smooth process interface to prevent waste of resources.
The implementation of the above aspects depends on the continuous efforts of IPQC, and it is with the above support that this process is the real process to ensure the quality of output. Therefore, the work of IPQC has realized the transformation from process to process, so that the output is no longer the simple addition of inputs, but the value-added in quantity and quality.
IPQC methods mainly include the following methods:
Perform process audit according to the audit list-the basic state of the process, regardless of the product.
Process operation inspection-confirmation of materials, tools, auxiliary materials, methods and personnel
First article confirmation inspection-depends on the inspection of products, processes, equipment, software and parameters.
Record-true, clear and timely
Feedback mechanism between processes-timely feedback of relevant information
The early warning mechanism worked.
Non-conforming product control-identification, isolation, differential placement and statistical analysis
Material input-put the right materials into the right products at the right time, and record them in time and accurately for traceability.
Product standards-process standards, functional requirements
Conduct sampling inspection on the output of each process-confirm that the process is stable, fully capable and the product is qualified.
IPQC process inspection work content
Prenatal work preparation
According to the production plan, determine whether the BOM, ECN and color matching of the production model are consistent with the online materials, and determine the inspection specifications. If IQC feed has samples, provide them to IPQC and production inspectors to confirm whether there is online selection for feed inspection; When selecting online, IQC will guide the online operator to select according to the sample.
Whether the on-line materials meet the requirements of product BOM, whether a box (bag) is refueled in time from screws to cartons, and whether the types, models and specifications of on-line materials are complete and correct according to product BOM and ECN.
Whether to hang SOP/WI or not, and whether to arrange drawings according to process flow.
Work content in process control
Fill in the inspection report carefully on time (usually every 2 hours) and check whether all wristbands used in wristbands have been inspected and recorded; Check the electric batch torque checklist, check whether the electric batch torque of the corresponding station meets the SOP requirements of the station and record the report.
Check whether the soldering iron temperature of the label and station corresponding to the soldering iron checklist meets the SOP requirements and record the report, and whether the soldering iron has grounding and leakage prevention measures.
Ensure that there are qualified first articles and samples.
Check whether the instruments and fixtures are normal with the first article and samples; Ensure that it is within the validity period of instrument calibration; Confirm that the set parameters are consistent with the product requirements.
Whether the employee's operation is consistent with the work instruction, whether the first five products are followed from front to back, and then sample 5 /2H/ workstation again for confirmation.
Whether to focus on the inspection of new products and new employees, and the special selection, substitution, trial production and release must focus on auditing, recording and feeding back the results.
The operation shall be fixed, positioned and placed, and shall not be piled up. Handle it with care, and dismantle it only after employees pass the self-inspection and mutual inspection.
Are nonconforming products marked and recorded in time?
Any bad incoming materials and operations that lead to the abnormal use of materials and affect the completion of orders shall be sent in time & gt feedback.
Test stations (such as semi-finished products test, function test and appearance inspection station) with defective rate exceeding quality target should fill in> and track the processing results.
A. Normal production (mass production)
The single defective rate is 3%-5% per hour, and it is necessary to open a feedback sheet for quality abnormality treatment-engineering analysis.
If the total defective rate is 5%- 10% per hour, you need to open the feedback form of quality exception handling-engineering analysis.
B. Trial production of products
The total defective rate is 65,438+00%, so it is necessary to open a feedback sheet for quality abnormality treatment-engineering analysis.
C. Stop notice
Single defect rate per hour ≥5%
The total project defect rate per hour is ≥8%
Requirements: Engineering analysis needs to provide solutions online within 1 hour, and if there is no reply, it will stop online.
Are materials, semi-finished products and finished products placed with implementation status identification and signature?
Whether the inspection report records are complete, clear and clear at a glance, whether the total number, number of defects and defective rate are recorded every hour, and whether the daily production line QC inspection report has the total number of inspections, defects and defective rate?
Understand and follow up customer complaints and returns. Rework must be followed up, bad statistics and feedback of results should be kept, and "status quo", "existing things" and "site" should be kept.
Replace and record sockets, batteries, contact pads, etc. Timely test for easy wear (for example, the charging port of the charger is fragile, resulting in poor interface of the mobile phone charger).
Any operation, packaging and storage shall not have a potential impact on the quality.
When customers relax product standards and accept a certain function and appearance, they need to sign the form for confirmation or sign the sample.
Customers' requirements for product standard changes should be fed back to online PQC and QA in time to achieve the unification of standards.
Evaluate and review online PQC work according to QA sampling results, and make Zhou Du summary.
IPQC job responsibilities
