You cannot be prepared for everything, nor do you need to be. However, you should expect some standard questions to come up.
Questions about your CV
If there are any gaps in your CV, you ought to have an explanation for them.
Honesty is of the essence here. The same is true regarding unusually long periods of study. If you engaged in voluntary activities at the same time, this may sometimes even work to your advantage.
To begin the conversation, it is useful to be able to give a brief summary of one’s own CV. It is particularly helpful to incorporate your interest in the position at hand at this point. In any case, you should make sure that your interest in this specific job is clear throughout the conversation.
It is possible that you will be asked to introduce yourself and present your CV in PowerPoint format or with the aid of a flipchart during the interview. You will usually be informed beforehand if this is the case. The presentation should cover all the significant points on your CV.
Your expectations of the job
How thoroughly have you prepared for the interview? Use this question to show that you have gathered information on the company and base your expectations on the facts you have researched.
Questions about abilities and interests
Expect to be asked about your strengths and weaknesses. Avoid naming weaknesses which could be considered strengths, such as impatience or perfectionism. It is better to be honest, although you should not overemphasise weaknesses, and match each weakness with a strength. The same applies to questions on successes and failures. Choose successes which are relevant to your future field of work. With failures, you can of course branch out somewhat into other areas. Nonetheless, they should be relevant to your work and hence enable you to cite lessons learned.
Try to gain an idea of the typical salary for your prospective position before the interview. Do not broach the subject of pay yourself. It is not unlikely that the employer will bring it up.If questioned, you should suggest a general salary range and be able to justify it. This always represents the gross annual salary. Refer to your qualifications, motivation and your professional experience. If a slightly smaller offer is made, you can negotiate but not insist on the larger sum. In this case you should bring up the subject again following your probationary period, or after a year’s employment at the latest.
