The CEO of client firm has reported that there has been increase in number of applicants for job at their firm by 50% but the growth in new hires has decreased by 15%. You need to help him/her investigate the cause.
[Please note that I stands for Interviewer and C stands for Candidate]
C: I would like to know more about the product the firm sells.
I: Firm is like TCS services and has similar operations.
C: How have the profits and sales grown in the said period?
I: The firm is doing well. There is in fact, an increase in the profits.
C: Has the competition also faced a similar issue related to hiring?
I: We do not know about the competitors and their hire growth-rates.
C: There can be two approaches to the problem. The reason could be because of either external or internal factors. Do you want me to look at any one of these first?
I: I would like you to tell me how it could be external and how could it be internal.
C: It can be external in terms of the macro effects such as general outlook of the service, technology needed by the employees in the domain, etc. It can be internal in terms of factors such as product outlook in market, promotions made for the work environment, place - work place (infrastructure) employee satisfaction, employee wages, company requirement of employees etc. Do you want me to take any one of these?
I: Yes. Please go ahead with internal factors.
C: Considering the increase in job applications we can look at promotions, salaries, place. Has there been any change in type of employees that are required for services that the client provides?
I: No, there has been no change.
C: Considering the increase in job applications again we can rule out employee satisfaction process, then we would be left with hiring process, has there been any changes in structure of hiring process, the panel, number of rounds, etc.?
I: No, there has not been any change in structure of hiring process.
C: Despite the increase in the number of applications the hiring process has not changed. This might have led to a situation where due to large volume of applications there is a delay in hiring process. Is the hiring process on first come first serve bases or best of interviewees model?
I: Yes, there has been increase in delay time because the company follows best of interviewees model. That would be it. Thankyou.
Your client is a lemonade seller in Lucknow, and he wants you to provide a strategy to expand his reach in entire UP.
[Please note that I stands for Interviewer and C stands for Candidate]
C: What type of lemonade is the client selling and are there any constraints that my client wants me to take care of?
I: It is a regular lemonade available in 2 variants, soda, and non-soda. No, you do not have any constraints and assume there is no investment restriction.
C: First, I would like to look at the factors that affect my strategy. From supply side would look at the raw materials, infrastructural cost, production process cost and distribution/logistics cost. From demand side, the reach of customers towards the shop, the competitors, etc.
I: Good, now how will you choose the locations(cities) for your expansion in UP.
C: Since we are not restricted on the investment that we get, we can think in terms of demand, first in short run I would be looking into metro and tier-1 cities like Noida and Kanpur. In the long term, would focus on tier 2 and tier 3 cities.
I: Well, now considering that you have a lemonade in Lucknow how would you price your lemonade?
C: The pricing can be done in 3 ways, cost based, competition based, and value based. Since we are having no investment restriction, I would go ahead with competition and value based. First, I would like to consider an additional value of the lemonade to be Rs 3. Given high investment, I would like to assume that we are using high quality raw material and equipment and thus, producing high quality lemonade. With the cost assumptions that paper cup costs Rs 2, Rs 2 for raw materials, Rs 3 for processing and a margin of Rs 2, the lemonade for competitors is priced at Rs 9. Adding the value to this, we can say that the price of lemonade should be Rs 12 for our client.
I: Good, I think that sums up the case.
