1. Structured Interview , Here, every single detail of the interview is decided in advance. The questions to be asked, the order in which the questions will be asked, the time given to each candidate, the information to be collected from each candidate, etc. is all decided in advance. Structured interview is also called Standardised, Patterned, Directed or Guided interview. Structured interviews are preplanned. They are accurate and precise. All the interviews will be uniform (same). Therefore, there will be consistency and minimum bias in structured interviews. 2. Unstructured Interview This interview is not planned in detail. Hence it is also called as Non-Directed interview. The question to be asked, the information to be collected from the candidates, etc. are not decided in advance. These interviews are non-planned and therefore, more flexible. Candidates are more relaxed in such interviews. They are encouraged to express themselves about different subjects, based on their expectations, motivations, background, interests, etc. Here the interviewer can make a better judgement of the candidate's personality, potentials, strengths and weaknesses. However, if the interviewer is not efficient then the discussions will lose direction and the interview will be a waste of time and effort. 3. Group Interview Here, all the candidates or small groups of candidates are interviewed together. The time of the interviewer is saved. A group interview is similar to a group discussion. A topic is given to the group, and they are asked to discuss it. The interviewer carefully watches the candidates. He tries to find out which candidate influences others, who clarifies issues, who summarises the discussion, who speaks effectively, etc. He tries to judge the behaviour of each candidate in a group situation. 4. Exit Interview When an employee leaves the company, he is interviewed either by his immediate superior or by the HRD manager. This interview is called an exit interview. Exit interview is taken to find out why the employee is leaving the company. Sometimes, the employee may be asked to withdraw his resignation by providing some incentives. Exit interviews are taken to create a good image of the company in the minds of the employees who are leaving the company. They help the company to make proper HRD policies, to create a favourable work environment, to create employee loyalty and to reduce labour turnover. 5. Depth Interview This is a semi-structured interview. The candidate has to give detailed information about his background, special interest, etc. He also has to give detailed information about his subject. Depth interview tries to find out if the candidate is an expert in his subject or not. Here, the interviewer must have a good understanding of human behaviour. 6. Stress Interview The purpose of this interview is to find out how the candidate behaves in a stressful situation. That is, whether the candidate gets angry or gets confused or gets frightened or gets nervous or remains cool in a stressful situation. The candidate who keeps his cool in a stressful situation is selected for the stressful job. Here, the interviewer tries to create a stressful situation during the interview. This is done purposely by asking the candidate rapid questions, criticising his answers, interrupting him repeatedly, etc. 7. Individual Interview This is a 'One-To-One' Interview. It is a verbal and visual interaction between two people, the interviewer and the candidate, for a particular purpose. The purpose of this interview is to match the candidate with the job. It is a two way communication. 8. Informal Interview Informal interview is an oral interview which can be arranged at any place. Different questions are asked to collect the required information from the candidate. Specific rigid procedure is not followed. It is a friendly interview. 9. Formal Interview Formal interview is held in a more formal atmosphere. The interviewer asks pre-planned questions. Formal interview is also called planned interview. 10. Panel Interview Panel means a selection committee or interview committee that is appointed for interviewing the candidates. The panel may include three or five members. They ask questions to the candidates about different aspects. They give marks to each candidate. The final decision will be taken by all members collectively by rating the candidates. Panel interview is always better than an interview by one interviewer because in a panel interview, collective judgement is used for selecting suitable candidates.
