A job interview costs nerves if you are not properly prepared. In addition to your professional qualifications, it's important to behave favourably during the interview if you want to get the job. Here are some typical mistakes you should avoid at a job interview.

1. being late. If you don't turn up on time for an interview, you show a lack of planning ability and even a lack of interest in the job. If you are late for the first interview, you give the impression of being a notoriously late employee.
To be sure of being on time, you should enquire about the address and route beforehand and plan an extra quarter of an hour.
If everything goes wrong and you are late despite being careful, you should call your employer in good time and let them know. This at least shows a sense of responsibility.

2. refuse support. All employees of the new employer should be treated equally. You should therefore not appear arrogant towards "lower" employees if they offer help and support. If you do not treat employees equally during the interview, you are unlikely to create a good working atmosphere.

3. go to the interview unprepared. Before the interview, you should enquire thoroughly about the company and the work tasks. If you make an unprepared impression, this shows a lack of interest. Good information material can be found on the company's website and in the product range. Good preparation is characterised by intelligent questions to the employer.

4. exaggeration. Everyone should endeavour to present themselves in a positive light, but shameless exaggeration of one's abilities and merits damages credibility. While you should be confident about your abilities, honesty is still key.

5. greed for money. The question of salary should not be one of the priorities, as an open display of greed is unflattering. The question of salary should be dealt with later in the interview.

6. badmouthing the old job. It's never a good idea to complain about your previous boss. Not least because your new employer may know your old boss. The reasons for leaving the previous job should be kept as neutral and brief as possible.

7 Showing too much emotion. Even though emotions are human, it doesn't make a good impression if you show too much emotion at a job interview. If you can't control your emotions, you are not the first choice for the job.

8. talking too much. Although the candidate is at the centre of the conversation, an uninterrupted stream of words comes across as self-centred. Answer the questions sufficiently but not excessively and do not take control of the conversation.

9. denying your own weaknesses. Anyone who answers evasively when asked about possible weaknesses is not showing enough honesty and self-criticism. Someone who is not self-critical cannot improve.

10. appear too desperate. If you appear too eager and keen for the job, it can damage your chances. The employer does not want to get the impression that they are doing someone a favour, but that they are hiring a useful member of the company. If you are too eager for the job, the employer may quickly doubt your actual abilities.
