    Candidate A=A Candidate B=B
    A: I am going to interview several candidates for the position of receptionist.
    B: I’ve heard that. Do you have any ideas?
    A: Sure. First of all, I’ll look at the candidate’s qualifications to see if the prospective receptionist has attended a secretarial training program or some other training courses. I also would like to know whether he/she had a proper educational background. Generally speaking, the higher his or her educational background, the better. What do you think?
    B: I agree. It is also important to consider whether he/she has experience as a receptionist. Is that right?
    A: Yeah, it is really of great significance. If the receptionist has related experience, he/she will help our company in a big way. As a matter of fact, a good receptionist does more than just representing the company’s image and he or she will also leaves a very important first impression of the company on the customers who come to our company. That is why the company is concerned with this.
    B: Well, I understand that your company is an international company, so I think it is necessary that the receptionist is able to speak English. Is that right?
    A: Absolutely. It is not enough that candidate can speak English since he/she will also take a lot of calls from our general headquarters in America and therefore is required to take notes. It certainly is not easy, but the qualified receptionist will be offered high wages. Another thing we need to consider is the candidate’s character. We should know if the candidate enjoys talking with or listening to people and how well he/she can get on with others. Do you agree?
    B: That’s just what I am thinking. The candidate’s manner is essential as well. It is beyond everything that the receptionist has a pleasant manner and a desire to improve. .
    A: Exactly. Nice talking to you about this. You have been very helpful.

    A: That’s reasonable. What else do you have in mind?
    B. I am thinking the salary can not be too low. With a low salary, I don’t know if I will still have the motivation to do the job well. Nevertheless, the salary should suit the importance of the position. What do you say?
    A: That’s for sure. Although salary is very important, it does not mean everything. Compared with the salary, I think the responsibilities of post are more important. More responsibilities mean the greater importance of the post..

    A: Since it is the first time for our company to attend a trade fair in Paris, I think we have to do a lot of preparations beforehand. What’s your view?
    B: I agree. I suppose we need to bring a lot of introductions, samples and brochures of our products with us. At the same time, it is advisable that we prepare free gifts printed with the name of our company so as to promote our products in the fair and pursue sales in the future. To make our exhibition special and attractive, I think it is important that we invite some experts to help us with the designing of the exhibition stand. We must make every endeavour to make our exhibition a success. What do you think?
    A: That is right. I think we should also arrange an appropriate schedule. For instance, we should get there several days earlier to have enough time to settle down and prepare for the trade fair. As is known, travel fatigue, climatic changes, jet lag, foreign food, etc. will all have some adverse effect on us.
    B: I wholly agree with you on that. And we need to book air tickets and reserve accommodations beforehand. As we all know, the accommodations will be difficult and more expensive due to the fair.
    A: Yes. Therefore, I think we need to contact a travel agency for it can offer a variety of choices and discounts to us, which will save us time to be better prepared for the trade fair.
    B: That’s just what I am thinking. Then, we must warn every member of the group of cultural differences, which may cause misunderstandings, so they should learn more about French culture before they go.
    A: Can you give some examples about the things the participants should do?
    B: Sure. For example, basic business customs that our participants should bear in mind include shaking hands with everyone present, inviting your customers to a lunch rather than a dinner, avoiding talking about business over the main course, etc.
    A: I can’t agree with you more. What do you think about us inviting some French people to give lectures and helping the participants know more about French culture?
